I'm getting a code "P-0303 Misfire Detected in Cylinder 3" from the emissions tester, so won't pass as the Service Engine Soon light keeps blinking. Spark plug in Cyl 3 had some oil on it. I blew out the socket, changed the rubber tube and the plug but the error will not remain cleared--keeps coming back. I wanted to switch the coil packs around to see if the problem is with the rear coil pack or something else instead. I can't drive with no tags/registration, so before taking to a shop I want to be certain what the problem is. ThanX!
Are the coil packs interchangeable on 2000 SLS? on 2000 Cadillac Seville SLS

Yes you can swap the coils to see if the problem follows a certain one!, very good test by the way! This may sound silly, but mark the #-3 coil with a piece of tape or the like before removing it, just in case! They all look alike after removal.
Thank you, but please understand that this SLS has only 2 coil BANKS/CASSETTES(front and rear), each cassette supplying 4 cylinders, so my intent is just to swap the front bank/cassette to the rear, and the rear to the front to see if the problem switches to cylinder 6. Is this still okay?
I know what you mean now! 4.6L No maybe not! I dont think it will hook up. I really do not know.
