Idle issues

[bluebyu]

I have a 2006 gt with automatic. When at stop lights the idle goes up to 1000rpm slowly. Does it with ac faster but does it no matter whats on or off. I have sprayed all hoses and connections for leaks found nothing. I cleaned throttle body and mass air sencer there is no codes shown at all. Any ideas Im stumped.

Mods?

Does the idle climb up and stay up? Or does it start to surge up and down?

Do you have the ability to datalog?

Still have charge motion valves. If so check to make sure they open and close smoothly. If not may need cleaned.

Maybe spray some dry film teflon around the TB blades and shaft. After I cleaned my TB, my car idled a little high. Dry film teflon significantly improved the idle.
Don't use silicone!
