When im in N and at a light or just running the engine it idles really strange. It goes below 1rpm and starts to shake a little then it spikes up to 1 1/2 rpms and then it kind of repeats.
Any ideas or suggestions?

Change your spark plugs?
It's not uncommon foe the factory plugs to come with improper gap or get fouled after a couple years.

anytime i've had a surging idle in a car, it's been the air flow/pressure (MAP or MAF) sensor. Not sure if that's the case on the jeep, but it kinda sounds like the computer can't figure out what's going on.
