Doucett Posted February 27, 2008 Share Posted February 27, 2008 Good Morning Gentlemen, My LS400, 1998 has been having a engine power problem for several days. Just replaced all of the coil modulars, plugs, but #2 plug still misfiring. Check engine light still on. Question...has anyone seen this problem on LS400 1998 before, and if so, what actions did you do?? Thank you for your inputs Quote Link to comment Share on other sites More sharing options...

VMF Posted February 27, 2008 Share Posted February 27, 2008 if you get cylinder 2 misfire, take the plug out and check for spark. it might be a bad spark or bad cable. Quote Link to comment Share on other sites More sharing options...
