97 Sunfire vibrating

[Jeffinur]

I have 1997 Sunfire GT 2.4L. Just had the engine redone and replaced. When pushing the gas the car starts vibrating the dash and insides of the car and sounds really loud, but just inside. When at a constant speed, the vibrations are not as bad and when pushing the brakes and being idle there are no vibrations. They rechecked the motor mount and made sure everything was tightened. We are at a loss for what it could be, any ideas?

i have the same problem, turns out to be a motor mount, upper right hand side to be exact. if you havent figured out the problem, you may want to check out your mounts.
