shaking and idle problems

hi my mom has a 1989 accord se-i two door. it shakes alot, but soemtimes when u stop the revs go up and down and up and down with out even touching the gas. do u have any idea what that is or how to fix the shaking.

i'm having the same problem in my 91 Acura Legend. Idle bogs up and down and starts to shake, evens stalls from time to time. I havent really checked on what could be the problem for me. But as for now...fuck it
