hi guys I have a sienna 2001 1.6 when the car heats up and I come to a stand still the revs climb extremely high when I pull away the revs comes down as normal ,any remedy .

Idle revs are controlled by the IAC valve.
Maybe it's broken, happened to me as well..
You can find inexpensive replacements on Ebay.

Any progress yet...??

Or maybe just lube the throttle cable....
