I have a 2003 H2 with about 90,000 miles on it. I'm getting a vibration from about 1500 rpm to about 2000 rpm, no matter what gear I'm in. I cant tell where it is coming from. I have also recently had my speedometer go a little crazy. I'll be driving on the freeway going around 70 and it will show 45. Other then that, it runs great. Anyone have this problem or have any ideas of whats going on?

 

I sent my H2 to the dealership so they could give it a good once-over and they said it was fine. The felt the vibration was caused by the exahust...possibly a vibration through the firewall. So as of now, I'm good to go...with a little vibration.
