1995 BMW 750iL 5.4L Poor Idle Quality, MIL Lamp on
Posted to European Driveability on 2/18/2004 11 Replies

Why would the DME think every cyl on this bank is misfiring? It does intermittently seem to drop rpm, but it does not idle rough or misfire at any point. DME1 and 2 both report these codes. Clearing codes and restarting brings them back after about 3-4 seconds...
