2002 Cadillac DeVille 4.6L Misfire, MIL Lamp on
Posted to GM Driveability on 2/24/2009 12 Replies

Hello Everyone... MAJOR headache here....

Put new Dealer motor in. (Reason)Coolant leaking into cylinders. Runs Great at idle. Go to take off and have check engine light flashing and see misfires on the scanner on Cyl. #1 and #4 only under load. Feel alittle...
