Did you try correcting the ignition firing order, from the ignition coilpacks, leading to your spark plugs? Also Unless you have a PCM scanner, or has had your Buick scanned, & know for sure you are in fact having a misfire, I would look into your fuel system (fuel rail, fuel injectors, fuel pressure check.). You may have a clogged injector spraying at two or more of your cylinders, causing a misfire.... I hope this information could help you. mdjblue78@Yahoo.com

random or multiple cylinder misfires detected. what kind of plugs did you put back in the car. The Chrysler 2.7l is picky about the plug types used. Some brands will cause excessive missfire and give this error even though they are new. Go back with the same plug that the vehicle calls for.
