Unfortunately, not the same problem. Mine bucks like poor gas or cylinder misfire, but neither are occurring, and the engine rpm is rock solid. Got a call yesterday that an engineer thinks it is caused by the exhaust system... but I think the front differential carrier bushings sounds more like what is happening. Time will tell as the dealer will look at it more next week.

And again to all, the local Hummer dealer is trying everything and is being responsive - it is a GM design problem that appears endemic to all H3s, more in some than others.
