Hi I have a 03 H2 I have a miss fire on cylinder 6 new wires still there new plugs still there moved coil packs around still there???

Has anyone experienced this is it because of fuel? Injector? or is it a gasket?? Any and all suggestions welcomed <img src='http://www.canadianhummerclub.com/forum ... /smile.gif' class='bbc_emoticon' alt=':)' />

[/quote]try and change the injectors around 6-8 and see if the miss moves to injector 8 if you do need injector let me know I have many new take outs

if you need any service done on your truck in the Toronto area.. there is a great couple of GM Trained Hummer Technicians that have they own shop now in Brampton and can do GMPP warranty work as well..give Steve or Jeff a call at Master Mechanics 905-455-8888, tell them Derek sent you..
