1991 Chevrolet C1500 Cheyenne 5.0L Hesitation, Surge, Cuts out, Misfire
Posted to GM Driveability on 3/25/2003 16 Replies

Thanks for your time. There are no codes. When the connector is disconnected to set the timing it runs very rough and rich even if the timing is correct. While driving there is a slight hesitation on takeoff and then at medium to light acceleration it cuts out...
