rough shut off

[97ebaygst]

I've been having a problem with my engine, when I turn it off it shuts off very rough. It feels like its falling apart. I don't have any problems while running only when I cut it off. Could it be a motor mount? I just changed the front one so I know its not that.

it very well could be a motor mount.

with the car off put it into gear or park then rock the car from the front bumper with the hood open and see how muxh movement you have.

Or just rev it a bit (just a lil' tap on the throttle) in neutral and watch how much the motor moves. Probably your rear motor mount.
