lately my car is having trouble Idling properly, but only happens when its hot (above 90). when i stop and the rev drops, it takes a while before it finds the idle, and when its really hot it cant find it at all, and the car stalls.

I think its my TPS cause i recently installed an ITR TB on my B16A2, but i had to use my B16 TPS cause the TPS was damaged on the ITR TB.

 

TPS maybe? Try swapping MAPs with a friend and see if it functions properly.

 

Make sure you have no vacuum leaks and using the proper gasket.
