2000 Cadillac Seville SLS Q&A
2000 Cadillac Seville SLS Question: Are the coil packs interchangeable on 2000 SLS?
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! - CaddyMac
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. Just saying. - pushrod
