2006 Chevrolet Express 3500 6.0L Misfire
Posted to GM Driveability on 8/24/2010 12 Replies

Intermittent misfires mostly on 1 and 8 cylinders. will run like a top and then some cylinders will misfire about 20 times then be good again. Has coil over plug. I'm kinda stumped because it won't misfire long enough, but when it does it's a dead miss.
