ok so here is the deal i have a 85 GT and it sat for about six years while i was in the army... now that i have it back i thought ok new battery upgrade the carb and im good to go... wrong!!! since i have had it back i have replaced the fuel system tank to carb... also a new coil and voltage regulator. the car runs really good for a while and then its like its missing or something... when it does this i noticed that the clock cuts out at the same time so thats why i changed the voltage reg and put a new coil in but what do ya know its still happening. so now im lost and don't know what to do next... can anyone help me...PLEASE!!!...
