Hey everyone! I have a tough one here! I have a 99 camaro that was a 3.8L and dropped in an LQ9 6.0L. It has the LS intake manifold and an Edelbrock throttle body. I got a used wiring harness for a 99 Z/28 and had the computer calibrated to the current specs. Right now I don't have the O2 sensors connected cause I still need to go to the exhaust shop. It fires and dies unless given partial throttle. It accelerates through the rpm range but has some backfires while doing it. I connected a MAC scanner and checked the readings. It is showing an IAT reading of 244 before I even start the car. The TPS idle readings are bouncing around when it does start. At idle I'm getting between 2.4 and 18 abslt%. I adjusted the throttle stop with engine off to .4%. After it starts it doesnt return to that setting. Any advice would be greatly appreciated!!
