Rough Idle and Hard Shaking

Rough Idle and Hard Shaking
I have a little bit of a rough idle on my 1996 Accord. I am going to be checking for that soon. The thing that I am wanting to fix first is that the car has a hard shake at random times. It only happens when I'm idling.
I notice it most when the ac is on, but it also happens when its not on. Does this have anything to do with the rough idle problem?
I have read a lot of threads about fixing the idle but I wasn't sure if there was something else wrong that needed to be addressed.

What do you mean "rough" idle? Vibrations? Or the idle RPM surging up & down?
It might be 2 aspects of the same problem, so I'd fix the idle & see if gets better.
Watch the tach when it happens. Does the idle RPM drop low at the same time?
Also watch the AC compressor clutch - see whether the AC engages at the same time.

Just me but you just got the car, can you rule out the tune up items - cap, rotor, plugs.
Also give the rear mount a good look - from the factory with the ac on there is vac applied to it.
I'm leaning towards the tune up or IAC......Does the "bad idle" when the ac is off seem to come at the same time the cooling fans cycle?

It looks like the the cap is pretty new. I checked the plug wires and they look good except one. One of them seems like they need replaced.
It seems like it is worse when the car is in Drive. When I switch back to Park the Idle seems to get better. It is still not great, but better then when I have the car in Drive.
I will check to see if the cooling fan causes the problem. Thanks
