Angry Engine Miss?

I have a 1984 jeep cherokee pioneer with a 2.8 liter v6. When driving around it is fine like getting up to the speed of 55 mph but when trying to maintain that speed the motor misses or chugs while trying to maintain a steady speed. Any ideas on what the problem might be? or where to begin to look? any ideas would be greatly appreciated. Thank for the help!!!!, Wayne

pull the plugs checkout the cap and rotor wook at the plug wires. or just do a complete tune up. then check compression mabey timing, and or cylender leak down test to check valves and rings if low compression. i would just do a tune up tho.

check vaccuum if it doesnt idle very good. and i assume it has a carb. clean that out too.

x2 on the plugs and ign. system. At night you can mist water on the wires and a crack or split in the wires will show up while its running.

Thanks for the help guys, turned out it was a bad ignition wire going from the coil to the cap. One more thing, while I was under the hood looking at all the miles of hoses I was wondering what would be wrong with taking off the smog pump and all of those lines that go everywhere and capping off all of those ports including the little tubes that go to the exhaust manifolds. I just want to clean up the engine bay so I can see the motor. Is there any problem with doing this? I would also like to get rid of the charcoal canister next to the radiator and cut and plug all of its lines also. P.S. The A/C can go bye bye also. Any sugestions would be appreciated.

you should leave the charcoal canister but the airpump could go and make sure you cap the injection ports for the air induction system on the exhaust manifold.
