Default Re: 74mm Throttle Body, surging idle

All connections are sound and everything tight.

All I had time to do yesterday was disconnect the MAF and the negative battery terminal (30 minutes minimum) to get the ECU to reset. I test drove twice, and other than a little higher idle, it was fine. I got in this morning to go to work and the problem came right back.

I am going to swap the MAF sensor and see if that helps. Next move is to take apart the TB or swap back to the 68mm. I will keep updating the thread for the next guy
