[ALVARADO302]

Hey guys maybe you can help me out. My 90 Fox GT has been having trouble in the morning its starts right up but it cant hold a steady idle...It will shut off, I turn the key car starts up with no problem but I have to keep my gas peddle pushed for about 3-7 minutes until it gets warm and then its ok. Dont know whats going on??? Thanks guys

Agreed. I would clean the IAC first off (w/o messing with the idle settings). That very well may solve the issue, and without introducing more variables.

Good luck.
