need help, car stalls with AC on

June 11, 2005, 08:57:47 AM

I appreciate the assistance I’ve gotten here. I have an 86 Cougar 3.8L TBI, 68,000 miles with auto and air. With recent electrical issues like the car stalling while driving I replaced the TFI which was needed after seeing condition of it. Recently added refrigerant to car and found it leaked over time so I decided this time to add sealer then refrigerant. Sealed leak and air conditioning is working. Now the problem, afterwards I drove had the car and it stalled once in which I waited 5 minutes and the car started and drove without any more problems. The following day I started the car and it idled perfectly and even put on air, normal, in idle without problems. Engine temperature looks good. When charging car with the sealer and refrigerant, the maximum AC position was used with a problem either. With air on normal and the car idling I decided to accelerate the engine which started to accelerate then quickly died. When thinking back the original electrical problems started just after I first charged the system. The car runs generally well but this bizarre electrical problem is now surfacing and has something to do with AC. Also, the throttle sensor looks in new condition. Any suggestions on troubleshooting ?

pull the codes yourself with a buzzer or a test light.
start there so your not throwing parts at it.
