No high idle or fast idle



My 1993 Corolla Wagon has No fast idle ever. It could be -20 out and it will start on the first try and chug untill it gets everything moving. The ac will still kick the idle up when it is on?



Anyone have any suggestions.

Sounds like a stuck Idle Air Control (IAC) valve. There are a few threads on how to check and clean the IAC along with the throttle body. I think Kiwi-Corolla wrote a DIY for it.
