2005 Hummer H2 6.0L Misfire, MIL Lamp on
Posted to GM Driveability on 6/4/2012 2 Replies

ok,this will sound weird but i have a strange misfire issue [...] 2000 and 3000 rpm in park or while driving # 1 and #6 will show misfiring as if the plug wires were off. both follow eachother like a mirror [...] is no actual misfiring that can be felt at all....
