Default starting and idling issue

Getting to be failry common where the car starts and just about quits but then catches itself. Sometimes it fires but then dies right away. Tonight it did this but then would not start but then did finally start after quite few trys. Otherwise it runs great. After reading through history it sounds like I should clean the IAC valve. Any other suggestions? It does have a PO128 coolant code but I think is unrelated.

you can try cleaning it and clean the seat in the throttle body. also check fuel pressure, most times when pumps go they fade out

No vaccuum leak codes hidden in there?

Default update

Took IAC out and cleaned it and the internal parts really good. Lots of carbon built up. Ran for about 30 minutes starting multiple times. No issues so far. Also no codes for vacuum leaks. Still concerned about fuel pump and will check pressure.

I read this at 4am this morning, and was so foggy it didn't dawn on me what the issue was. Duh, but I would think your correct Mark. Cleaning the IAC valve usually does the trick.
