Here is the story, I test drove the car for a few days, it had nice power all around. I took it back to the dealership because of a noise which sounded like a wheel bearing goin bad. They had it in the shop for 2 days, they changed brake rotors, tires, and inspected the water pump (he said they would be removing it because they thought it was bad)

My question could they have knocked the motor out of time by removing the water pump and doing something improperly? Or is the car being slower all in my head. It is a significant difference in speed and its seeming to rev higher to get up to speed than it was before i had it in their shop.

Thanks guys
