97 1.8 High Idle

So I've gotten my car running pretty smooth. It was idling fine around 800~ depending on if the a/c was on or off. Saturday night after I wiped a quick 180 the idle shot up to 2k and has been holding steady there.

I got carb cleaner and sprayed every vacuum line I could find with no detectable idle change. I didn't have much left with what was sitting on my shelf so going to buy another can tonight and spray all over again. (Intake gasket for sure I didn't spray it at all last time.)

I have a spare tb with tps/iac on it. So I may swap the whole thing over and see if anything changes. Any other suggestions ? Car is running great otherwise.

I swapped to another tb with a diffrent tps and iac and the car wants to idle at 5k now with adjustment screw all the way in.

I bench tested this tps and it seemed fine. Also used a can of carb cleaner before I swapped the tb and found no leaks.
