Possible bad PCM/ECM
IF I unplug the battery the tune is gone. If I dont drive the car for a few days it doesnt run right. Had to reflash the tune in it again on Tuesday. I am thinking the CPU is bad. I want to make sure before I spend the money and not solve the problem. I am useing HPT to tune the car. When the tune is reflashed the car runs like a champ
