1989 Porsche 911 Carrera 4 3.6L Bacfires on Start Up
Posted to European Driveability on 5/29/2002 8 Replies

at times with hot or cold engine it will backfire and blow boots off intake. engine runs smooth when it starts. no hesitation and runs well down the road. hard to diagnose when it starts and runs well.
