how about your o2 sensor? check the sensors with a multimeter before you replace anything though. a leaky injector will let the pressure bleed off your system and into one cylinder when you turn the engine off. your oil will have a strong gas smell and be watered down. also, one spark plug will be really black compared to the tan of the others.

you can pull your injectors and clean them though. get some carb cleaner in a can and spray them really good. then you can put them back in and fill the rail with seafoam and then hook the fuel line back up and start the jeep up. it will crank for a while well the seafoam is running through the injectors and then fire up when the fuel pushes the seafoam out. it'll smoke for a bit but once your done, it will run smoother as the injectors won't be partially clogged anymore
