My car has been idling really weird ever since I install my BLox 70MM throttle body. It goes from 1K rpm to 2K rpm flunctuating. Whenever I replace my body I remove the FITV, could that be the probleM? if so there is no place to place the FITV in my new throttle body.

 

jump your service connector and play with the air flow.
Also make sure you have a new gasket and there are no vac leaks.
my guess is a vac leak.
no you dont need the FITV

 

Ok, thanks I make sure I had no vacuum leaks. So I'm guessing TPS
