I have a 1994 trans am, lt1 motor that was just rebuild. New cam, and headers. Had the computer reprogrammed for all the work that was done. this thing will not idle right, keeps going up and down. All the sensors, and i mean all!, are new, the opti spark is also new. I've attached the data log from a Solus Ultra scanner of it idling. I sure hope someone can look at that log and see what's wrong with it. We are all thinking the shop that built the motor didn't line up the cam and crank right, but before we rip back into the motor I hope someone here can give some advice. thanks for reading, and feel free to ask more questions!
