Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Default 03 HUMMER H2 issues .

I just purchased A 03 Homer H2, and my RPM won't go past 2000 . My MPH works fine. Just trying to find out what type of good advice I can get before I go to a actual shop?

Default Looking into a very dark tunnel with no flashlight!

Any addl info, Check engine light, pop's sputters, gauge info, all normal readings. In park tapping the gas, can you get the RPM's to go over 2K, Do you have access to a scanner? How many miles? I guess at least it runs, thats a start.

Need more info, is it running fine and just the tach that is not reading right? In that case a cluster repair will be needed, if it is not revving over 2000 RPM, I would suspect a clogged catalytic convertor.
