my tuner cant get the car to idle. It idles in park but when put in gear it dies. I just did heads/cam, stock ported heads 2.02/1.60, 234/242 .598/.610 114. Using 7.4 pushrods. He was doing a speed density tune, no maf. They tried swapping out the tps sensor but that didnt do anything different. The heads were milled 4 thousandths to make sure there was no warping. Is that enough to change pushrod length needed? I need some ideas to give them. Alot of time has been wasted trying to fix the problem with the computer. I need my car FINISHED by today, sunday 11-5, before i go out of town for work for several weeks.
