Service Engine Light
I came out of the gym today and when I started my H3 it seemed to idle kind of rough, like it had a cylinder miss firing. as I drove back to work the service engine light came one. Please tell me that this is not the infamous head problem. Was too late to call the service department, will call tomorrow to get them tow it in.

Re: Service Engine Light
I hate to say it, but that's what mine did when I had to get it to the shop. Turned out to be the cylinder head. Bummer.

Re: Service Engine Light
I Love when the service department a) changes the rules as they go and b) know nothing of a on going head issue. They had been real good abou tcoming to pick up my H3 from work saving me an hour drive and having to take work off but he said they changed thayt rule just this morning...
I then asked them of they had any ideas and they said it is probably just a plug wire. I asked them about any one else having trouble with the head and their answer was, we have never even heard of that. I asked them if they have any one that follows any of the HUMMER fourms and he said that there would be no reason to do such. I guess no one would benifit from keeping the pulse of teh owners
