I changed the plugs first off and I figured that would be it, because the old plugs were rusted and BEAT. I put the new ones in and it runs worse than it did before.. help me out with ideas. Thanks

Your wires could have been bad before you switched plugs, and by moving the wires around during the process, it could have made them worse than before.

I don't have wires. It's a coil rail

Oh, my bad. I just did a wire swap on my 89, so i was assuming your jeep was the same as mine.

No your good. I have an 89 also. But this 2000 is BUGGIN. I don't know what it can be.

Ya this 89 has been a pita. I just got done building it up to a 4.7 and i had to go through all of the electrics and i finally got it runnin yesterday. It has no exhaust yet and that thing is loud! Sorry i cant help ya.

Sounds awesome dude. Congrats. Good luck

Thanks a lot man.
