you could replace plugs, wires, cap, rotor, air filter, fuel filter, maybe even fuel pump, check vacuum lines for leaks, tranny fluid flush, etc. lots of stuff to check for a hesitant motor.

Before doing anything else, let me suggest something I got from a 20yr veteran Jeep mechanic....
Run an entire can of seafoam through the intake and then immediately shut off the engine. Let it sit for a couple of hours. Then take the jeep to an area you can do this without getting in trouble and do 15 to 20 minutes worth of back to back 3000+ rpm runs. The soak time will loosen up any crap on the valves. Jeep valves begin to rattle at 3000 rpm's, knocking the buildup off. Essentially, it is a poor man's valve lap.

TV cable adjustment? It gets a little stretched after a while, and if its hesitating during pedal press maybe thats it.
