Good morning all,
john jay you hit the nail on the head! First thing I did was lower ADC Scale to 2.50 and the car immediately responded. I moved the RPM and PPR settings in the drive and MSU to achieve the most stable speeds I could and the car has been running since Tuesday. My natural curious side wants to know what must have changed in the system that necessitated the change in that parameter that was set from the day the car was adjusted 25+ years ago? I am very thankful that the damn thing is running! Thank you all very much for your help with this!
