Has anyone had a problem with the engine reving up to around 2500 rpm when the clutch is depressed? My H3 will rev up occasionally for no apparent reason. I reported it to Lynch Hummer, and tehy in turn notified GM. GM says they are aware of the problem, but until enough people report it they will not do anything!
If you have a similar issue with your manual H3, please get it reported to your dealer! They say it is a PCM programming issue...
