Ok so I have got it all mocked up and set up. I drilled a 5/8 hole in the 45 degree joint for one of the sensors, but what do I do with the 4 inch tube mass air flow sensor can it be deleted? I saw on this car he isnt running it. I am just wondering because my 85 is giving me codes since its not hooked up to the air flow.

I tried to search nothing came up.

small cyinder above filter is what I am refereeing to.

 

he doesnt even mention what to do with that MAFS? execpt the one I already took care of. So I am stumped and want a cleaner look without that thing dangling there. Also dont want the codes popping up. Would really appreciate some input.

 

or would my best bet be to incorporate it somehow and if so how should I go about it?

 

Incorporate it as close to throttle body as possible.

 

Agree with the above. With no MAF sensor your not metering the air correctly at all. You have a MAF car. With your current ecm and fueling set up you need to have it hooked up right and try to place it close to the TB like it was stock.

I have a speed density car for example, which does not have a MAF sensor nor does any of the 3.1L's on thirdgens. So whos car did you see that on?? MAF can be deleted but there is alot of work to make that possible. And in your case it wouldnt be worth it.

BTW that CAI isnt going to help much as its still breathing in hot air from under the hood. A dual snorkle would of worked best but since you fabbed that one up some sort of box arround it would work good to. It does look nice though but isnt going to help much as for grabbing outside ambient air.

FYI 1986-1989 came with a dual snorkle intake IIRC

Also Ill add that there is no way in gods creations that a CAI will net 10 HP on a basically stock 2.8L-3.1L thirdgen. So I must dissagree with what was in that link above. A delta 260 grind cam is pressed to add 10-15hp.

 

Also thanks for the placement answer. I have yet to box it in .....like I said I just set it up. and I am still in MOCK stage lol. Just needed to know where to put the MAF. But thanks for the input. So the closer to the intake the better the reading? Cool shouldn't be too hard. Thanks again guys.

from my old 85. the flexihose ting had a pvc ube in it, smooth flow to the tb.

just a suggestion.

 

Put the MAF in a good spot. and all aired tight. Still getting check engine light after the bird has warmed up any suggestions?

 

Reset the ecm. pull out the fuse that is on the fender well right next to your air filter. Unhook it for 1 minuet. Or just take off the negitive battery cable for 1 minuet. see if that takes it away.

 

awesome thank you!

 

Yep did what you said early this morning. Engine light was off. But it began reving the engine from 700 - 1900rpms and almost dying when went it went down. Not sure how normal that is. But when I first got her, she would just warm up rev around 1200. Then on my way home from work the light was back on and the car was running great. As this is my first bird. And I am used to dealing with older vehicles. ECU's and computer programmed vehicles are just to much for me sometimes. I have been reading and learning as much as I can on these birds but every time I search for these problems there is no salvation nor diagnosis. I think I should just go back to the stock intake set up and go from there. Makes to much sense for it to work correctly. Try to give the engine more air and it chokes lol. Oh well what do you guys think?

 

Well I kept digging and I forgot to take out the mount for the original air canister so The filter pretty much was choking it out. It still needs a little more room. But is running much better and without the engine light on. The launch response is very much enhanced from this up grade. The other cylinder near the same location I re-mounted under neath using the same plastic studs that were on the original mount just underneath. running sweet and sounds amazing.!!

 

It was reving like that becasue you need to do the idle relearn proceedure before you drive it. Im short on times so google "idle relearn thirdgen". And youll see the correct procedure. You must do this everytime you reset the ecm.

 

1. No idle relearn before 90.
2. Birds can't do the dual snorkel intake due to hood-to-radiator clearance.
3. Probably needs to remove the IAC and clean it and the passage out good. And also check the ends of the idle air bypass pipe for cracks and damage and also the rest of the vacuum hoses for deterioration along with valve cover, PCV grommet, and PCV breather tube elbow sealing. And possibly reset the minimum air rate.

Also make sure there are no air leaks between the air filter and the throttle body. MAFs tend to not like them. Screen end of the MAF goes towards the air filter. And don't put it close to the TB.

 

thanks guys. Engine light was on because it wasnt getting enough air. I made more room for the filter and solved everything. I understand the "procedure" is just sitting and letting the car run while the ecm figures it out on its own which is exactly what I did un-knowingly haha. Thanks for all the help I am having a lot of fun with this bird.

 

opps I wasent aware that pre 2.8L didnt have a idle relearn. Sorry op

 

no it does. at least I think it does. haha

 

Check you throttle body and clean all the carbon off.

 

Cleaned the IAC throttle body looked good surprisingly. Cleaning the IAC valve did an amazing wonder to the launch response and the weird idle problem. The procedure went incredibly smooth. Thanks for all the help guys. Keeping my bird on the road!
