i noticed when i was sitting at a light that my engine was idling way high, it was almost at 1500 rpms, i know i can take to my friend and get my friend to adjust with his scanner, but i was wondering if anyone had any ideas why this started happening? confused.gif

the engine is supposed to run a high idle when its cold. there's actually a name for the program with in the ECU that does this, but i forgot it (stupid). but 1500-2000rpms is really high. mine goes up to 1400rpms on a really cold day. i'll try to find out what toyota calls this automatic idle adjust again.

Yeah I think it's called an Idle Air Control program for the
IAC Valve, it bleeds air away from the throttle and so controls the idle according to coolant temp etc.
It was the first thing that was checked when I had a jumpy
idle on my first Celica.
