Idle creep when warm
So i i finished doing the vac line replacement now i i have an idle that is super smooth, but creeps up when it gets warmed up. Stock ecu, downpipe and intake. New plugs, grounds...etc. since the rpms start to creep up only when it gets half way warmed up makes me think gasket. Thoughts?

So how much is the RPM's creeping up?
Do you have the thermowax? Does the car do the 1500 RPM idle when cold and then it comes down?

So it doesn't ever come down to an 800 RPM idle?
Either you've got a big air leak somewhere or the TB is sticking open somehow. That's a lot of air getting into the engine.

Well let me preface that a bit. My tach isnt really reliable so not 100% sure but it sure sounds like its its creeping up. I already adjusted the screw under the tb and that brought it way down but it still creeps up. Plugged my smoke machine up and didnt see any vac line leaks. Then again it only happens when the engine is abt half way warm or higher.
