01 Jeep Cherokee Sport Idle Vibration
So here is my issue. I've got a 2001 Jeep Cherokee Sport. When sitting at idle, the engine shakes and vibrates. I can feel it most on the gas/break pedals and the floor directly under them. The shaking isn't anything drastic, but I know it's shaking more than it did when I first purchased it a year ago. When I start driving, the vibrating seems to go away until I actually stop the car again. There doesn't seem to be any issues with power, and the engine sounds normal. It is definitely worse in drive or reverse. I am noticing now that changing from park, to neutral, and then to drive is causing more a "kick" in the car then it did before. There seems to be a more drastic bump when changing gears.
The jeep has 63K miles. I probably took it out to the beach about a dozen times last summer, and that's the extent of it's offroad use so far.
My first thought is motor mounts, but I wanted to see if anyone else had experience with idle vibration on a cherokee. I'll be able to get a good look at it this weekend. Any ideas??

X2 on the motor mounts. hows your idle? high, low? the engine will move around a bit more when it's idleing to low.

Thanks for the replies. Idle RPM is 900, but every 10 seconds or so it surges up to 1000-1100, and then back down to 900. Thinking about it now, I don't think it was doing this before, but I also wasn't looking out for it. Based on other cherokees, is the idle RPM and fluctuation abnormal?

Great. I'll do these things this weekend and also take a look at the condition of the motor mounts. Thanks everyone for the advice. I'll follow up with the results.
