Crisis

Ok it's a sunny day over here and i had a little spare time so i decided to pull the error codes that i've had 1 in two weeks (played with the amp and had to disconnect the ground. i have had more codes. don't know what thou didn't pull the codes)

(btw.sorry for the spelling..)

The problems i've been having with the car a basic ones for a car this age.. the biggest problem i've had is the engine stumbling in ideal. the stumbling doesn't start untill the engine goes out of enrichment mode. even with enrichment when i push the gas half way the engine almost dies. 100-200rpms then picks up and rev to 3k fast.. it does that only the first time i start the car each day.. I can smell fuel and i'm positive that it's running w/o all the cylinders.. spark plugs are fine..

The second problem i have is that i'm loosing engine coolant.. i know for sure i don't have a gasket leak or dropping forem the car so two possibilities.. cylinder wall/head to the combution chamber (crack or something) or the radiator cap.. it does this bubling sound right away when i turn my car off when warm... i lose 1-2 liters per week... the first time i noticed the problem the radiator was completly empty

now for the codes.. these codes it gave me at the same time.. codes 12 and 43...

i've tried seaching for info about code 12.. it's "Speed reference pulse" what ever that is... haven't found any.

and code 43... thats "ESC" according to my manual.. i read that it has something to do with the knok sensor??

performance was crappy with the old rear... i got 9.2-10 sec times for 0-62mph runs (0-100km/h) while i hear that it shoud have been around 8 sec with the lo3 and 2.71s...
the engine has 78k now on it and started giving me s*it last fall...

now that i've just done the rear swap i've got around 8sec times.. thats a good improvement for just a rear swap.. but still it doesn't feel like the car that it was 2 years ago...

I haven't had a chance to test the car with summer tires yet.

could someone do a quick diagnostic based on this info.. i'll tell you more info if required...

And thanks already for atleast reading this..

(i have read that people have had simular problems but i haven't seen any that have solved tham..)

Crisis,

What you are referring to as "enrichment" is commonly called "open-loop" mode, where the ECM has no reliable feedback from the oxygen sensor while the engine is being warmed to operating temperature. In this mode, the fuel mixture is indeed rich, and several other parameters are skewed to accelerate the warm-up process and allow the engine to run without the O² sensor feedback.

Your two error codes are '12' and '43'. The '12' is for missing distributor reference pulses, meaning that the ECM is active while there are no distributor pulses being generated. This is normal in the KOEO test mode, since the engine should not be running. The '43' is an Electronic Spark Control failure, caused by the lack of a knock sensor signal or excessive spark retard. I'd suggest checking the knock sensor and its wiring, and the ESC wiring itself (including grounds).

Your misfire is not normal, and may be casued by a faulty ignition system, vacuum leaks, poor compression on some cylinders, or problems with fuel injectors. Since you have the L03, the injector problems are less likely. You'll need to check that out before you can reliably diagnose the rest of the problems.

Red Devil

Just out of curiosity, how old is the O2 sensor?

Crisis

the o2 is original i'm gonna check it and the tps today... but it isn't giving any lean or rich codes....

Crisis

"The '12' is for missing distributor reference pulses, meaning that the ECM is active while there are no distributor pulses being generated. This is normal in the KOEO test mode, since the engine should not be running"
now what does this really mean?? do you mean the car running even thou it shoudn't?? you go me confused..

the code 43 know that i know what to do i'll clean and check all the connection relating to the ignition.. see if that does anything... i did mess a little with that ingition wires today... on "seemed" to be loose.. well a least when i pressed it i feelt a small click.. i've never had to even touch the ingnition. so i doubt know one has ether.. btw the cars been in my family since new for the dealers... it was moms daily driver..

i have the formula hood opened up if better flow... could this have gotten snow and watter in the engine bay (yes it has but does it have very stong effects??) it's been open for 6 mounts and i was just to lazy and stupind so i didn't put it back on when winter came... we get about 3-5 feel of snow per winter... and thats a lot...

The car was burried for 2 mouths in snow while i was in the service...

injector work well... no drips and they spray very well..

Vader

Crisis,

The "12" is normal when you perform a code scan. Any time the ECM is active (ignition is ON) and the engine is not generating distributor pulses (from the distributor turning) the code "12" will set.

If the engine compartment was buried in snow, you may have moisture in the distributor cap, damp wires, wet spark plugs, and other parts contaminated with water. I'd suggest removing he distributor cap and rotor, them cleaning, drying, and inspecting them. If you were in the US I'd suggest simply replacing them, but I can imagine that parts availability may not be that common in your location.

Crisis

how'd ya guess about the availability i can get parts... availabilyty is basicly good but so is the price... to compare my car costs about 10000€.... the rear and exhaust swap cost me 900€... vss 60€ and so on... the engine wasn't coverd by snow.. im just saying i know some got in there... is the anything special i need to know about cleaning the distributor cap and rotor?? i do have a chilton's manual. is it worth reading?? (i have done so and only posted it it didn't help)

oh and i'd like to say thank you.. i've been reading this board much longer than i have been posting and you have really been one of the few who's nicks have stood out from the rest.. well atleast me and a friend (who's a big v8 fan) thinks so.. thanks again..

Vader

Hints for cleaning the distributor cap? Use no solvents or harsh chemicals. Just mild detergent and hot water, then allow the parts to dry completely.

I misunderstood your post. I thought the hood was open and the engine had a couple meters of snowfall on it.

BTW - That's about the right price for a VSS - in either Euros or US dollars

Crisis

ok.. so i got winaldl working finaly..

I think i have a tps problem. i tested it with the engine off... the max values i got were 95.3%.. the strange thing is that when the thortle is at 1/3 i get a ~15-18% thortle at half i get 30%.. the 95.3% i got by standing on the gas peddal.. i even tried turning the thortle from the tb to be sure its not the cable...

I'm not very sure about the o2 sensor.. the reading varies from 0.014v to 0.972... i drove around for 30 min in the city.. the reading jumps from side to side in every rpm range and map value... is this healthy?? the rough average is around 0.4-0.5v but i see lots of hole full of low or high values... very strange.. i even got 0.420v at 400rpms, 0.010v at 800rpms when map value is at 100... i didn't exeed 3500rpms.. but i did some small launches..

well you could have guessed by the o2 values that blms are all over the place.. at map values of 20 and 30 its very well in the 128 range. a little over or under but mainly dot on... when maps at 40 i get low values mainly... ~124. Here starts the fun part... after map exeeds 50 it get very nasty. allmost all of the reading go over 130.. a few 128s at 2000rpms but i get alot of 137... mainly 128-137.4 with an average of 135...

no error codes were set...

i have no idea of what INT is but its pritty well around 128.. +/- 4

i don't know if this is relevant but my spark counts are a mess also.. i'm getting reading from 1 to 245... 245 being at 400rpms and 95 map...

knock counter got #222 but i cleared that table 5 min before my laptop battery gave away..

i have a reason to suspect that iat's bad to... 46.3C 115.4F.. its 5C outside in the sun... around 0C in the shade... hmmm.... this is a average..

maximum map was 100.8kpa

iac was 160...

coolant temp 184.7.. isn't that way high???

hmm battery voltage was 0 volts... well my audio system was working very well compared to that value

Could somebody clear this mess up a little..

i'm getting a new o2 sensor this weekend and plug wires (accel)

any info will help next weekends project.. were doing the ultimate tbi mods and adjusting the spark timing..

Btw... i got some rich flags.. it flashed a few times..

help me??

Crisis

c'mon guys... someone has to know something about atleast one of the small problems.. or is it just one small thing throwing everything off??

Vader

Crisis,

The TPS should be acceptable. 95% at WOT is more than enough. Anything over 80% is interpreted by the ECM as WOT conditions. What's more significant is what's below that point, especially at low and intermediate throttle angles.

The O² sensor is apparently operating as it should. Voltage should constantly vary around the 450mV bias voltage applied by the ECM. Teh "swings" above and below that voltage are called crosscounts, and you seem to be generating an ample supply to indicate that the mixture is in control of the O² and ECM. If voltage remains either above or below that bias voltage it would indicate a rich or lean condition, respectively.

INT is the Integrator. It calculates short term corrections from the Block Learn Memeory and over sufficiaent time, will adjust the operating conditions beyond the base lookup table sprogrammed into the PROM. A value of 128 means that conditions are almost "perfect" since the range of values used by the ECM processor are from 1-256, so 128 is exactly halfway, or "perfect" midpoint conditions.

Your knock counts may indicate a low octane or too much intinial timing advance.

The IAT is actually measuring the temperature of the bottom of the intake plenum. 115°F is probably about right for a fully warmed engine in cooler outdoor air. Much of the plenum heat is radiated from teh engien or conducted through the aluminum intake parts.

Your IAC counts may be a bit high, indicating you may need to clean the TB and readjust the throttle minimu air position.

Your coolant temperature seems to be about right. You need to reach at least 176°F to achieve full closed-loop operation. Stock engines were equipped with a 195°F thermostat, which often regulated coolant temperatures near 220°F.

I'd say you have a connection or interface problem, since 0V at the battery would have prevented any of the data communication you got.

So, exactly what's the problem again? Other than cleaning the TB and checking out the timing and knock sensor, you might be ready to run.

Crisis

Vader,

I think we may have had another misunderstanding about the crosscounts.. what i meant is that the avg. jump around...

For example.. i got 49 counts on 1200rpms and map at 20... average was 0.290v
and so on... weird numbers..

If my blms are around 132-136 when at 50% throttle shoud i be concerned about being lean?? should i rase the fuel psi????

I noticed i didn't get any values in the blms durring wot.. is that normal?? how do i know if i'm going lean? i loose power after 3000rpms very fast... like driving into a wall..

People say that they are shifting at 5k (with close to stock lo3s) but i get faster launchs at 50% throttle than at wot and shifting at 4k. thats one problem i'm trying to correct... anoter is my 11mpg averge in the city...

the timing was set by a local shop... i doubt they even knew about the jumper you have to put in the diag. terminal.. dumb asses (i gave them the chilton manual when i had my brakes fixed up front. got a tuneup at the same time for no labor costs.)

today was a better test drive day... my knock count was 24 total. mostly i got knock at higher revs (2500-4400) with very low or very high map.
Could the knock sensor be dot on?? that could explain the bad mpg and slugish movement (even thouw its a lo3 i could expext more that 8.2sec 0-60 times... with good traction.)

I got my *** handed to me by a 230hp 500Nm mercedes (E 320 CDI)... it was a close pull to about 100mph then i let off and he got passed.. he won by a 3 feet.. i doubt he knew how to drive LOL

ok the tps is fine.. not touching that..

I'm changing my old o2 anyway. i got 78tm on it.. should i set the timing with the old or new o2 sensor?? how about the fuel psi? new o2 in first??

Cured the loosing coolant prob by cleaning the radiato cap.. the valve was leaking into the (plastic little canister) and boiling away..

I played aroung basicly just turning the spark wire hats on the distributor cap... got all 8 working now even in open loop..

Spark wires i'm changing and cleaning the distributor cap and rotor..

set timing so that theres no knock.

gonna do the tb "shaving" thats in the ultimate tbi mods.

clean tb...

What else should i do??

Injector cleaner??

This project starts on saterday morning.. Any input up untill then is VERY VERY VERY welcome.

I'll get back with the results on sunday.. (if i don't blow the engine up in the prosess. if so theres gona be one thirdgener on the railroad tracks having a meeting with a train LOL up close and personal)

thanks for your help this far...

P.s this must be the longest post i've writen so far.

Crisis

oh yeah... about fuel octaine.. i use the europian 95 octaine fuel.. shoud i start using 98??

Vader

I'd definitely set the base timing myself.

WOT = Open Loop = No BLMs.

Definitely change the O², which may help the rich flags at part throttle.

I'm still looking at yout data table, trying to see what's happening.

Crisis

here are some of the tables... i would be nice if you could point out somethings to look for...

heres knock, it's alot better than yesterday (got 255 knock counts in 5 min)

Stange thing is that i drove around for an hour and got allmost empty tables.. the green indicator in winaldl blinks once every second and the value in that box is 20?? is that good or bad.. i know it indicates how good of a connection is formed.

heres BLMs...

What is correction???

I'm starting to get the idea how the ecm works... now all i have to do is get a eprom burner and eraser..

hope this tells you some thing..

Crisis

if

wot = open loop then how do i check if i'm lean at wot.. (which i'm sure i am... )

You can use a dedicated Air/Fuel gauge, a wideband oxygen sesnor and recording meter or laptop data logger, or use an adjustable pressure regulator and measured times over distance to tune to bet WOT mixture.

My 305 was lean at WOT until I increased fuel rail pressure to about 43 PSIG with vacuum, 50 PSIG without vacuum. I'm sure your adjustment will be different.
