At only 44000 miles, you shouldn't be seeing trouble codes that aren't really there.
But then again, it is a Jeep. Those idiot lights get wacky sometimes.
I think a tuneup would probably be the answer, though. If your plugs and wires are old and/or are of a lousy quality, it might be time to replace them.
Let me guess, though: the original plugs and wires were swapped out around 30k, and you have new ones from a Jiffy Lube or someplace like that?
I would go with Chrysler plugs and wires only. They're pricey, but much better than KEM or Autolite or any of those other cheap brands.
Also, make sure the plugs are gapped correctly. In a couple of cars I've tuned up, I've found that the plugs I pulled out weren't ever gapped at all. That'll definitely contribute to some poor performance.
