Last night I went on Champion's website and read about their "Truck Plug". Has anyone used them??

Yup I have but in my plow truck, for your xj just run what the tag on the hood tells you to, this is what ran best for them in the factory.

A pic of #2 and #1 or #3 beside it (for comparison) might help in diagnosis.

All I could get was a real crappy pic of # 2

I'm a big believer in there being a reason the manufacture did what they did. And if you're going to change it you better have a damn good reason for it.

As an aside what would be the stock plug wire set for a 94 SE?

The pebbles came out clear. LOL, a tannish color is normal. Are u getting a cyl #2 misfire?

jeepin4fun97

Yea that and sometimes a random miss fire?

Has it set a CEL with a cyl code #?

ummmmmmmmmm...how about 20+ years of research and new technology?

Also, sometimes manufacturers do what they do for cheapness.

for the NGK ones are you talking about the NGK V Power copper spark plugs?

I just pulled a set of those Champion DP plugs. I don't know how many miles were on them since I bought the Jeep used (has 97k on the clock) a week ago. Was getting a P0303 (cyl #3 misfire), and a P1294 (Low idle) CEL, and at time really crappy idle. Surer than anything #3's plug had a gap that you could slip a penny through. Replaced all the plugs with regular Champion Copper's. Hopefully the Jeep will be happy now. From experience with a 2001 Neon it too only liked Champion Coppers. It had the distributorless ignition as well. Go figure...

What's the code #?

Yep that's right

What are the signs that "it likes Champion Coppers"?
