I wonder if anyone has an idea of what may be the cause if this symptom? I was sitting at a stop light and all of a sudden, the CF "choked" almost dies but caught itself immediately and kept running. then I noticed very slight pulsating of the dash lights, very slight. When I got home and parked, I noticed that all lights were pulsating. This is with the car engine running. Any ideas of what this may be caused from? Voltage regulator, battery, alternator? Thanks for any input.
