I just put a new head on my 2.7 Its starts and runs strong but its idling around 2000rpm It trys to drop back to normal idle sometimes which lead me to belive it was the TPS but I put a new one on and no change. I traced all the vacumme lines and everything looks good I even sprayed starting fluid all around while it was running to see if I got a change and nothing. Im not getting a check engine light.
I was just wondering if anyone has any ideas. I dont want to have to put it on the dio.
