1992 Ford F Super Duty Custom 7.3L Poor Idle Quality, Misfire
Posted to Ford Driveability on 7/11/2009 15 Replies

Just bought truck recently, it has a misfire at idle, every 30 seconds or so it clears up & runs perfect, 30 seconds later it starts to miss. When missfiring you can hear a tick in the exhaust & slight blue smoke. Truck runs great down the road plenty of power...
