'98 ZJ 4.0 stutter/misfire issues
I'm having a little trouble with my ZJ, so I figured I would ask here before I start replacing parts. Occasionally my jeep runs a little rough. It sometimes happens, although not as bad when the jeep is first started. It only lasts a few seconds, and then fades away. The worst part is after the jeep is already warmed up and it is started. It runs fine for a few seconds, and as I pull out of the parking lot or whatever and head down the road the jeep will start sputtering/misfiring for about 3-4 seconds. Everything else seems fine with it, it has been happening for maybe a month now and didn't even give me any problems on my 1,300 mile trip two weeks ago.
Before my trip I replaced the plugs, wires, cap & rotor, and the air filter. I'm still not too familar with this platform, but I am guessing my problem could be a fuel filter, O2 sensor, or maybe the map sensor. Any thoughts? Thanks,
