naw dont worry about that. If the car isnt actually boucing its idle than its fine. If it is going up and down in revs first thing to look at is your Idle Air Control Valve. Older cars tend to have those needles that kinda "shake" around and ive noticed no side effects. My moms car between 20 and 30 now does it a bit but I havent noticed anything else.
