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.

Just to note, I was looking at my order from Qtech and found out that I have wires for a 2.5 XJ not a TJ. What would be the negative affects of this, if any?

Me personally, i would go back to the stock specifications and check your firing order. Also...I would get rid of anything that had the SPLITFIRE name on it. I've never heard of anything running better on splitfires. ( wires, plugs...you name it)

do you see any sparks jumping to the block from your wires? I've seen sparks burn through the spark plug boot and fire off to the block. Have you checked all connections? Firing order?

If it helps - Autozone will read codes for free. Best of luck to a speedy fix.

Come go for a ride and I'll be glad to demonstrate the difference between what you perceive incorrectly as "control" and what control actually is.

Pick a different reason because that one is both lame and stupid to perpetuate.

So, I checked my spark plugs, and one looked like this
http://www.imagestation.com/album/pi...?id=2106015726

So I went and bought champion plugs and standard wires. I installed them and still heard some arcing so I removed the aftermarket coil also. Now it runs great. I can actually do 75 now. I wish I had read this forum before I dropped the money on that aftermarket crap. Now lets see if Qtec gives me my money back(probably not)

Thanks

Not to rain on your parade, but if you spark plug comes out looking lke that, and it was new when you put it in, you've got some serious issues. But if its straightened out now, then just chalk that down to lessons learned.

I'd just leave it alone now. Most of that aftermarket crap is marketing hype - they just slap some pretty colors on there, give it a fancy box and charge 2x the price....a 2.5L is 2.5L and it'll always be that way.
