i have a 96 gt. the other day would not start at all. disoconected the batt to reset the computer and it started. now not idling right and it dies at redlight i have to rev to keep it running the idol is not to ruff just not constant. to be honest my filter on my cold air intake is not great need to be replaced. the onlt thing i can think of is the maf. any ideas

no check engine light car runs fine sometimes and idols fine sometimes i just have no clue

 

TPS would be your best start!while also cleaning your MAF...then IAC....my guess is on the TPS

 

Is it throwing any codes?

 

Found the problem I bought a deffective iac actually 2 deffective I a have the old back on I have to go and see to get my money back and get one from the dealer I guess I got to bad parts right out of the store talk about good luck

 

Maybe if you got 2 "bad ones" in a row, it's possible its NOT the IAC?

 

sounds like a IAC issue to me, but 2 bad parts in a row seems like its not that likley. However, they are refurbished from places like advanced and autozone (why they are so cheap), but if you buy it from ford it is brand new (and more expensive)

 

Ill ask cause you just never know now adays, you are using a gasket to seal it to the manifold right?

 

i fixed a small vacume leak then put the old iac on after i returned the other two. drove the car all day yesterday everything seems like its back to normal. yeah and i got them from auto zone i am pretty sure they where refurbished i can say i am no longer going to auto zone this is not the first time i have had a defective part from them but it is the first that i have had two in a row.
ill keep driving till the end of the weak and if the problem re-accurs i will go to oreily and get the name brand part or ford house (duralst is crap)

 

If you got a Wells IAC from autozone (same one I have) Its not refurbushed and wells is equivelant or even better than the factory unit.
