Answer 4

If you mean that when you accelerate from a stop, or after slowing

to a stop then continuing on, you feel as if the car gets a bump on the rear...either---

a) the EGS (auto transmission computer module) needs to be re-programmed;

b) or, the differential bushing holding the differential housing to the

rear sub-frame is torn/wornout.

Answer 5

Did you check to see if you ran someone over and their stuck under the car?
