Odd idling?

if im sitting in park idling my jeep randomly shakes . its not that noticeable but enough to make the broken stuff inside my cat rattle randomly... recent new stuff.

idler pulley water pump tensioner(pulley) ps pump original pulley. plugs wires cap rotor.
my ps still has a little squealing but i was told itll fix itself over time. my belt has a little dry rot i need to replace but its not noisy yet.

Anyone know whats up? does with heat off.

How do the motor mount look? Mine has a bad plenum gasket and it idles rough sometimes. It's fine after I put octane booster in.

To check the plenum you have to remove your throttle body and look way back towards the back with a bright flashlight. If you see any signs of motor oil then it's bad.

Check your motor mounts, clean out the IAC, replace the belt, buy a new converter. Start with the IAC and belt first, cheapest.

Did it do this before changing plugs, wires, cap, and rotor ? If not, recheck plugs are tight, wires on snug, cap and rotor on properly, and wires routed right. I vaguely remember a thread regarding a TSB about plug wire routing about a month ago, ( I've got an excellent memory, it's just real short).

There was a thread just the other day talking about plug wire routing, it had a TSB in it for the 5.2.
It had picture and instructions for rerouting. I guess it can cause all kinds of happy Jack crap.
If the wires cross each other they must cross at 90° to one another, not parallel

Don't get me wrong here, I'm not saying this is your problem.
I'm just passing along information that might be, or might not be a solution.
