Need help, jeep misfiring
I have a 99 TJ with a 2.5. I have recently put in a 4.0 Throttle body, a new muffler, high out put coil with Splitfire wires and E3 plugs gapped at .045(thats what the coil instructions said I should gap them at). I have 31 in Xterrains and stock gearing. I have nooooooooo power, and now my jeep is misfiring. I checked the distributer and was unable to locate any cracks and it looks relatively new. The things I think it might be are A). the plug wires don't actually have boots like the stock ones, they just sit on top of the prongs coming out of the distributer???? B) catalytic converter, but it seems more like an electrical problem. Also, I can hear an arcing sound when I listen with the hood open. I need some serious help. I am running out of patience and money, and not exactly enjoying my new jeep like I want to be. Also....I can't get the error codes from my jeep using any of the turn key on-off three times methods, or the hold down the odometer for five seconds and then turn on the key. So the next thing is to go someplace and get it tested, does VIP or Advance auto do that? Thanks for you help.
