k guys ive been having a problem with the car ilding low wen coming to a stop after warm up. i had the alt tested and it was bad so replaced with a know good one

still same problem so i think it might be a intake leak, nothing

is there a way to reset the IAC?

gonna check if thsi alt is also good or not

and after it is warm sitting at idle it just shuts off it doesnt stumble or anything just shuts off and will start right back up?

 

Sounds like either the IACV or an ignition module. Put a miltimeter on the IACV and see if it is within specs. I will see if I can some up with those specs.

Any CEL at all?

 

no cel

 

I would check that IACV to be honest man. That would be my first thing. Second, like I said, would be the ignition module. What year car and engine is it?

Put a miltimeter on the IACV and check it's resistance. Compare that to the numbers in a Haynes manual.

 

i have experienced the bad dizzy and it would have to cool down to start back up this will start right back up

ima take the iac off and try to clean it or check it out

i think it may be the iac

 

iac and fiv are good

 

make sure you ICV isn't wired backwards. It should close up completly when warm. If wired backwards it will also be backwards. iono maybe im wrong but its worth a try.

 

the iac always sucks in air to keep a idle

the fast idle valve stops sucking when it gets hot

they are both owrking properly

 

what about main relay?

 

wen the motor dies the vafc stays on along with the ecu so i dont think its the main relay

ive switched pumps also and still no dice

 

My last idea, the ignition module, as stated previously.

Don't know of anything else to tell you other than that.
