That's right. You shouldn't be driving it with that problem. Even though they are telling you that they 'think' it's a plug wire .. tell them you believe it's a safety issue and you won't drive it that way. That's what I had to do. My engine light came up and I felt the rough idle. I called OnStar .. they didn't see a problem. When I took it to the dealer they thought it was probably nothing and said they'd order a couple of parts and call me when they were in. I insisted they have a mechanic look into it more closely while I waited and sure enough it the cylinder head. I got my rental and got the H3 back in about a 10 days. Good luck and let us know what you find out. Hoping yours isn't what we think it is.

The H3 does not have conventional spark plug wires (with their inherent problems).

Driving it with the head problem is not going to damage anything any worse than it already is but I would still want it fixed asap...
Sorry to hear about your problem, it's probably just a matter of time for a lot more of us.

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.
