E3's = engine light?

I put the E3 spark plugs in Angel's Jeep tonight and the results weren't good. The engine light came on and she said that it now runs kinda rough at 45 but mostly clears up at 55+. Any thoughts on this? We put a K&N filter in on Sunday but that's the only changes we've made in the engine, has anybody else tried/had problems with these plugs? I know sometimes a small change will throw a light but spark plugs? Thanks for any help. So far her first Jeep is a pain.

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.

It's an 06 with the 4.0 I6 and yes the one-piece doohickey that replaced plug wires went back on fine, with no problems.

(I know they're making improvments all the time but did they really have to do away with plug wires?! I know I've been away from gas engines for a little while but come on, no plug wires?!)

That is the coil on plug setup. I know it is a pain but I would pull the plugs or a plug and check for the correct gap.

Can't; E3's are vehicle specific, you can't gap them.

I thought about that when I was putting them in but the way they're made you can't get a gap tool in there. It's hard to explain how they're made but it's a 3 point thing on top of the electrode that's supposed to increase the spark, but it also block three sides so you can't check or change the gap.

Ohh I know which ones your talking bout. No need to explain. Was it running good before you did the plugs?

Sounds like you haven't had a chance to check, but I'll bet you are getting a cylinder misfire code.

If that's the case, you should try to return the plugs and use recommended plugs instead of whatever kind of gunk "E3" is selling. Sounds like a splitfire plug with an extra electrode which is just like paying extra money for 4 blade razors. Only you don't get a CEL from shaving with extra expensive razor blades.

Get some autolite APP985's (note the double P). Double tipped platinum's in your TJ will last a loooong time and things should be well.
