sirII jdm b16a car was reving at idle 2400- 1000 back and forth messed with TPS and now idles at 2500. checked everything. made sure no vacum leaks. bled radiator. checked connections. cleaned butterfly. i dont know whats wrong. im thinking maybe a bad sensor anyone please give me a idea whats wrong.

 

Does this happen all the time or just when the car isn't warmed up yet? My guess is you've got a bad IACV.

 

What MrFat said, also, check for a vacumm leak. Spray with carb cleaner around all the gaskets and see if the engine bogs/revs.
