Please, I'll sleep better if I find out this is the problem, I'll explain the stupidity behind the question later

But anyway....

if the IAT sensor was never plugged back in, could that cause the car to run COMPLETELY SH**Y as soon as it goes into closed loop?

 

damn you guys, now I gotta go to bed wondering

...can someone answer it over night so I can know in the morning

 

sorry man... yea... it doesnt know the incoming tep of air... so it could just retard it and make it run like crap... sorry to answer late... i might not have the answer.. but at least i could try

 

I believe the system executes some sort of 'limp home' mode, so that the car doesnt get hurt and you can drive it around still. Least thats what I think.

 

no, wrong, if it is unplugged the computer will "see" that and either use a default value, or figure it from the ECT sensor at startup............it wont run ****ty, but the check engine light will be on

 

well, i took a stab at it.... anyway... i dont know... i dont have one at all.... it looks like the hole where it should go on the intake, its been patched, there are no wires or sensors... ive had the car since 87.... well my dad has... so my dad or me would know what happend..

 

If I remember correctly from a debate a long time ago, the IAT
serves no funtion really. The computer does not use it's input to
calculate anything. It needs to be hooked up to keep from
throwing a code but that's about it. I will look in the archives a bit
and try to find that thread.

Here is a thread that explains it.

 

well, I put one in this morning and it helped alot but not all of the problem. Got a few more things to do to try and get it rite.

I'll keep ya's updated
