car wouldn't start unless you push the gas, and would stall when you let up on the gas. Have replaced the Idle motor with 3 different ones, and it still won't idle right.
first one idled too fast, second one too slow, third one doesn't let car start without touching gas, and the car doesn't idle faster when cold.
Please help. Thank you.

If each one did something different, chances are I would try a different brand. Today, we import everything and chances are you got three bad ones. Also, was the check engine light on? Didi it identify the IAC as the problem?
