my car now dies unless i have the gas pressed when its warm for like 10 or so mins.i thought i had fixed the problem yesterday, to find a plug going to a fuel injector was loose, that wasn't it. it will run fine when cold but once warm, you can gradually see the drop of rpms as soon as i let off the gas. it will get worse and worse until the point of me letting of the gas and it dieing instantly. also a code 36 appears randomly sometimes, yet i have a new maf and all new ignition. i checked the fuel pressure, and its fine so the fuel pump is good. i also have a new fuel filter in. my prediction is that i have a bad/dirty injector(s), or some crazy case of vapor lock. am i right? i used an auto stethoscope to listen to the injectors but all seemed ok(what the book said). I also checked the resistance of each injector, and all were about 16.7 (books says between 11 and 14 i think) any help would be greatly appreciated, for it sucks driving with a foot on the gas and another on the brake (for now i only drive it 5 miles to school a day).
thanks

 

did you try checking the voltage to the idle air controller?

 

what is the code 36 ?

 

could be a vacuum leak that gets worse as the motor warms up

 

I had a split hose going to the T/B that made the car not idle at all. Had a mushy feal to the throttle aswell

 

code 36 is maf sensor burn off circuit. poor electrical connection, open or short in circuit, defective esc module, defective knock sensor, defctive ecm. i have also had a code 35 before which is idle speed control. this states tps sticking or mis adjusted, poor connection, defective iac valve, defective ecm. i have a good feeling it is the iac valve. is it the thing under the throttle body on the left, under that tps?

 

ok i haver the iac sensor out, its covered with carbon and stuff. how do i test if it is bad or not? i think i read that u should be able to easily push it in, mine does not budge. any extra help would be greatly appreciated.
thanks

 

Most likely it's a bad Maf burnoff relay gone bad.

 

is that part of the maf sensor itself or wiring further back?, cause i payed 200 bucks for a new maf sensor like 3 months ago

 

It's mounted on the firewall near the master cylinder. It costs about $10.00. I'm attaching a picture that someone took for me when I had your problem.

Good Luck

 

thank you very much guys, i really appreciate all of your help. i just bought a new iac and it seems to be driving ok, but i have a feeling it will act up tomm, so i will def use all of your input to try and find a problem.

 

you know you have to reset the minimum idle air right ? it's just getting it all buttoned up that will make the differance.

 

what kind of reading are you getting from your o2 sensor? your car runs off a fixed value until the o2 sensor warms to temp. take a close look at your o2 sensor.
