Hello all,

I have a 2001 camry 4cyl w/ auto tranny. the check engine light came on recently, and the only thing out of ordinary i have noticed is that when starting cold, the engine does not immediately go to warm up rpms (like 1900?), but instead hangs around 800-1200 for a few seconds and then goes up to warm up.

Any insight before I go find a scan tool?

Most auto parts stores will scan for free.

If I had to guess, I'd say the Idle Air Control valve was sticking, although it'd be nice to know the code that's being thrown.

If the code points in the direction of the IAC, I'd recommend heading over to the DIY thread ( http://www.toyotanation.com/forum/showthread.php?t=220549 ) , and find the directions for cleaning the throttle body (which also does a good job of cleaning up the IAC). There are more involved procedures for removing and testing the IAC, but easy stuff first...

It's a P0446

Autozone's scanner said that it's a P0446 (Evaporative Emission Control System Vent Control circuit fault). I'll check the threads about that. Thanks.

It is my problem too, precisely!
