Welllllll- it weighs a lot- and it's underpowered- do you mean it's slower than usual? How much slower? Can you describe the problem a little better? Give the Gurus somethin' to work with girl!

OK- it's ok to not know much about cars- but why drive a baby hummer? That's more like a guy car- is that what you really want? Or would you rather have something else? Sleep on it


Lol well i like it..

if your hummer feels sluggish- first make sure that you are up to date on all scheduled maintenance- according to the mileage on the vehicle and the maintenance schedule in your owner's manual- if you use the H3 for off-road romping or other hard use- do the required maintenance earlier than scheduled- don't cheap out- do everything- see if that helps

The H3 has a hi-tech I-5 motor - It runs much better if you use High Octane 93 gas. If the car is used, change the plugs, filters and air sensor.. The motor should run much easier once a few tanks of the high octane fuel run trough the system...it is a heavy vehicle, motor should wind out to near 6k rpm to get it moving

I think the majority of people aren't explaining right. The engine HAS power...it has a terrible hesitation when you want to all the sudden, go fast. IT JERKS ALMOST BACKWARDS.
