Are you sure it is the engine because my wife has this car, and the rear differential fluid was broken down and makes the car shutter. Check out this video:

Yep, the fluid in the rear differential breaks down and does not allow the differential clutch discs to disengage which makes the "bumping" sensation. The differential only holds less than a quart of their special fluid. Each quart is $75.00 at the dealer, and you must use their fluid. How many miles are on it?

We have seen the dealer replace the rear differential for $5,000.00 to fix this problem, so the fluid is a cheap fix. Please let me know what you find.
