Have some issues with my e36 1996 318i !!

[achnaide]

hi,

Two major things I got:

1. My car shakes on idle. I checked with mechanic and saw it my self on the computer check that my rpm jumps in range 780-810 rpms. What could be the problem.?

2. I hear squeaking noise on the bumps and holes from the right side rear wheal. What is it shocks or something?

Thanks
