Ok, Ive had this problem, and I really want an answer, cuz its bugging the hell out of me.

I have a 91 accord, and lately when I am at stop lights, the idle will drop, and the steering wheel shakes, and then it goes back up. This also happens more if i am pressing the brakes when stopped.

Another thing I figure that is linked is when stopped, and not touching anything, the motor shakes, but if you tap the idle up just a tiny bit, it stops. The idle is set at around 800 when warmed up, and setting it up higher doesnt help any. If the a/c is on, it also shakes pretty bad. The thing that comes to mind is the rear motor mount. I wanna know for sure before i go out buying one first.

Its just really really annoying. I have an AEM CAI and thats it for upgrades. As for replaced parts, I have done, plugs, wires, whole distributer, cap, rotor, pcv valve, timing adjusted, fuel filter, fuel pump, oils pretty new. It was colder than normal here a week or two ago, but its back to normal. And motors got 190k on it.

I also have a stereo system, but this was happening before i got it. and doesnt seem to have any effect whether on or off.

Thanks to any help.
