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

Plugs wires - the H3 doesn't have plug wires. I forget the proper name (maybe coil on plug??). The coil connects directly to the plug.

Coil on plug, I think is the term.

Well the service engine light went off on the way home, then came back on. it really feels just like a miss but I doubt that. I will give Hummer a call and see what they say.
