Since I had the plugs and wires done, I have a serious hesitation. I step on the gas I get a serious pause, kind of flat she may stall or not.
Under the hood, when I hit the throttle quickly, I hear a sucking sound, that seems to be coming from the area under and behind the throttle body, like a vacuum leak, I shot carb cleaner in the vicinity hoping that the engine would suck in the cleaner, rev a bit and give me an idea where the leak may exist, if it does at all. No luck.
I take off the throttle body, plenum and search for a cracked vacuum line ... Nothing. Damn plenums been on and off at least six time.
Any Ideas ?

Ok RC10PYP4, Champion Double Platinum from Mopar, were installed. Definite improvement. But I caused another issue. The Top egr tube bolt holes are stripped I guess. They go in spin all the way in nicely, but dont grab and tighten. No biggy. Got the spare from the wreck.
After installing the plugs, I took it for a 40 mile test run. I did get two minor hesitations but I think once the vacuum leak is fixed, the issue should be corrected unless something else pops up, or the minor hesitation increased frequency and intensity. Will keep ya posted.

I know that Chrysler Tech said Champion, but I have found NGK spark plugs to be better. However, if you stick to OEM, you can't be wrong.

Jeeps use NGK. I will tell u chrysler fuel systems build there calculations around the spark plugs. If u change the setting u get stuff like what happened on this post.

Well, I did some more poking around and see that the cylinders where the spark plugs sit are filling with oil. Not alot but enough to cover the plug lightly and Id bet that this is part of the issue. Next up, valve cover gaskets and seals and ofcourse fixing that @%$$## plenum.
Guess Ill take all the sensors off of the bad and put on the good just to be sure.
Will keep ya posted.
