My car runs! I even drove it to the nearest gas station to fill it up. It hesitates at various rpm's and dies often but I have found out why. It is running soley off of the battery so I have to jump-start it almost every time. I'm hoping the alternator isn't dead but I'll check. The confusing part is, and this should sound right if you have a MAP 4agze, the alternator harness is part of the body harness on the AE86 but the MAP 4agze has it as part of the engine harness which is the one I am using now, the original ae86 alt plug is just tucked away. Do I have to splice them together for it to work?
