replaced it with a used one who knows if its been dropped... but when i drove it on the dyno for a good while after for idling for 20 mins with a stable idle nothing, drove it for about a mile circle, took a right on arden, right onto hurley, and right onto morse back to the shop, nothing kept it at around 2500rpms, with a partial throttle to 3,000 nothing,
this thing is wierd....

Ya, hurry up and pop in a new O2, how long does it take to do that Eric, what kind of shop are you running anyway, lol, new O2 takes weeks to put in. Poor David has to keep waiting and wondering.

looks like eric's yankin' his dizzy out for me. If it is the dist. It could possibly be the pick up coil or?
I did test the module and pick up already. we will see.
I looked at Bennies Z yesterday....Damn clean sleeper.
My car will always wear it's factory red shade...sorry guys...gotta have it the same. I'm too picky to do a color change.
Oh and Bennie....I saw that sneaky looking exhaust on the Z.
I will have to get my electric three inch cutout put on just after the cats for a bit more at the track.

i doubt its rockers.
like i say, keep it red
especially if thats what it came with from factory.
btw i had an electric cutout, wasnt thrilled with it, the design of them makes them prone to leaking. mine did, all they use is some rtv to seal it when its closed.
keep that in mind, im gonna do cutouts again but ill stay manual next time.

Most likely not the rocker adjustment, too tight you'd have a surge at idle,always..probably not too noticible at higher RPM..., too loose you'd here the "clack" and know before you ever took it in to get fixed.
Also, a quick monitor of intake vacuum at idle would tell you where to look for mechanical or ignition issues...but seems there's only a problem at 2500 now?
That's good.
I'd monitor Rich/lean flag and open/closed loop during the surge and see if it's related. Also would want to know the number of O2 crosscounts during the surge too. May want to disconnect the AIR (if it's still on and active), I've experienced bad diverter valves flaking with the AF readings.
Was an injector balance test run?

well no news yet...id like to readjust those rocker arms with you just to verify....did a vaccum check what day was it like last week sometime and it pulled like 10inhg or 15 dont remember and it was steady though thats what i do remember,
the rocker arms make some noise above idle when holding steady thats why i would like to just readjust them
what you otta do is come down here and bug bennie hahaha
dont tell him to take his time or he will
it seems that the idle doesnt surge any more its just a misfire...

that sounds good eric- the re-adjust of the rockers...
what about the misfire?
can we just let it idle and then pull plug wires one by one until we find the miss?
I guess we can spend one day pulling your upper and adjusting my rockers and oh yeah, put in your x-box.
let me know.

we didnt want to strip the crank bolt cause it was so tight to turn, so we orderd a crank turning tool you remove the pully and bolt it to the harmonic balancer and use that to turn instead and actually it just got here yesterday rockers should be adjusted by monday

Ace mechanics say 323.00 I'll get it somehow.
Eric says idle a bit ruff still..thinks injectors..
Hey Eric-
did you guys set my f.p. up for me as well?
is this thing all adjusted so I don't have to mess with it other than injectors?
Bennie wants to hire me to do ALL the rocker adjusts out of his shop!

you guys are funny
. the car accelerate/pull harder now after the rocker arm adjustment. also the tapping sound coming from the right bank is no longer present. however, the idle quality does not meet my standard. it doesn't have that rythm i expect from a ZZ4.
IROCDADDY,
are you going to run it friday night? it's ready to
let see what she can do in the 1320.

I gotta tell ya, no offense to the shop, but take it as you see fit.
6 weeks to figure out that a misfire is actually a surge ? (see my reply as to what mis-adjusted valves would cause)
If you can't tell the difference between a surge and a misfire, then maybe it's best to stick to stuffing the stick up the tailpaipe and putting the car on the roller.
ad "adjust" the IAC? Cmon, I gotta know how the "adjust the IAC" was done...unless someone went into the PROM, but if that person had that knowledge, then there would be no issues with an idle quality.
I dunno, maybe the " Problem Statement" wasn't clear to me, but I do know for a fact, that valve adjustment and IAC is no resolution to a "misfire".

so dont go bad mouthing a shop unless you know the story,
and well this car had multiple problems it wasnt just the rocker arms were mis adjusted, the distrubtor wasnt shimmed properly causing play, that o2 sensor was bad, and the idle needed to be raised so as far as im concerned

hey guys come on no fighting amongst us please...I think what eric meant to say is that the shop is mainly just for smog diagnostics, but are always willing to help out a friend if they need their car worked on. Since David didn't exactly need the car right away, I'm sure its understandable that doing that much work to the car should take several weeks. But ya it was David's own word to let them work on it, its not like its their specialty (although I'm sure they do just fine).
So no more fighting.

Yeah I guess I'll chime in here before it gets more retarded.
To somebody who hasn't been to the shop, it's hard to understand how things work there.
I've been taking my car to Bennie before most of y'all were even on these boards and can vouch for the work in general.
The priority for in->out right away IS smog and general repair, but providing an in-depth diagnostic/high performance or major work where time is not a major concern to the customer is worked out with Bennie prior to leaving the keys.
Not that I'm saying 6 weeks is to be expected, but you do get quality work there and are not paying massive labor charges for the amount of time that is actually being spent under the hood.
I've taken my rides' in there for small stupid stuff that's taken a couple hours or the occasional big job that's taken over a month.
You just need to be prepared beforehand with what you need and how soon you need it.
If you leave it wide open, he will take his time and only touch it when he can.
Hope that clears it up a bit.
