I am wondering if you have an air intake boot that is torn can you check it for tears please.

Also a video of the problem would be helpful please upload it to Youtube and then post the link.

This would be for the mass air flow sensor. While you are at it cleaning the mass air flow could help as well.

Here is a guide

If the engine is running okay, it sounds like you might have an engine mount problem. If the engine doesn't vibrate in reverse then check the mounts and get back to me please.
