I have an 89' sahara yj 6 cyl. 4.2L T. and long story short my engine started to run a little rough and wouldn't start without pumping the gas a bunch. so i decided to replace the distributor cap, rotor, and new spark plugs. now its running even rougher and sounds like there is a definite miss fire some where. so i started pulling plug wires trying to find it until i "shockingly" noticed that every time i pull a spark plug wire the coil wire would arc out every where from the top of the coil until i would plug the wire back in. so i went to the local napa and asked for some ideas and he had told me that i needed to replace the spark plug wires so i did. now the engine starts without pumping a ton of gas through it and idles close to perfect. but as soon as i give it gas or start driving the miss fire is really very noticeable in noise, feel, and loss of power. could the coil, distributor< or something else need to be replaced? or could i have gapped a spark plug wrong or install one crooked? any ideas help!
