Hi, the above "only when cold" idle jumps up and down. After engine warms up idle is fine. It was stalling when I would put in gear or go around corners but that was resolved by replacing IAC motor/valve. I have lived with the cold idle for about a year but thought I would try and maybe resolve. Only other weird issues, yellow check engine light goes on and off intermittently. If I have the heat defoggers on and push the gas pedal way down it switches the heat to the feet until I let off the gas. So some kind of vacuum leak under dash but I cant find it. Recently passed smog test with no problems. I am thinking maybe the TPS but I would think that would cause a problem all the time and not just when cold. Thanks for listening.
