Won't Idle When Cold (Stalls)

[jtbel]

I am having to give it gas until the engine warms up. This is only when engine is cold. If not the engine will shut off. What parts can be attributed to this problem? I already cleaned the iacv as best I could. How do you test it to see if it still works? Other than the iacv, what part could be at fault? Thanks

Check the engine coolant temperature sensor,if it's faulty it may be telling the ECU the engine is nice and warm when it is in fact cold so the fueling will be incorrect causing the stalling.

Thank for the reply. Is there a way to check it? I had replaced it about 2 months back.

Was it OEM or from a parts house?

From Autozone.

Check for vacuum leak on intake ducting. If a duct is cracked or not fitted properly it will pass air that won't be detected by the MAF sensor and could mess up EFI trimming by ECU.

You cleaned IACV but did you clean Throttle body too? If it is caked up with carbon that could add problems too.

cleaning the iacv only helps if it is still working , if it has been glued stuck long enough it is dead
