AHHHHH..... I love stupid people

[FlexdXJ]

so i was tuning up the jeep yesterday and I swear the plugs and wires were the stock ones. The gap was like 45 or 50 thousandths and the wires had mopar written on them. If i meet the guy that owned my jeep before. swift kick to his nuts. Hey she runs better now though:yelclap:

Awww man...when I gapped mine I went that big... (.045) But my wires said Mopar TOO! And the plugs I took out were .075-.080"!!!

 

[FlexdXJ]

bet it ran a little better huh

AHHHHH let me check mine

Is it really common to have them gapped wrong...? going to check mine now...

HV Erosion. Next time you install a set of plugs, write down what gap you set them to. Check about every six months - you'll see it get steadily larger.

yeah its kinda of like the edm machines we have at work only they work a lot slower

That's exactly what it's like - and probably where they got the idea for the thing.

EDM is just more controlled. HV Erosion happens willy-nilly, while EDM can actually cut an (almost) perfectly square hole on the first go.

when I bought my xj he said he used syn oil I asked about the plugs and he said he never touched them...

the looked newer, it would idle rough and my gas mileage sucked so I pulled one out and they were split fire but there was no tip left. I proceeded to change the rest and on another one the porcelan was crooked I touched the it and it fell right out..
good thing I changed them

the rest were just as bad as the first. I have no idea how it ran:dunno: before

Or it could have been serviced at a Jeep dealer. :dunno:

when I first bought my jeep I tuned it up because it wouldn't idle. The timing was off by more than 10 degrees. that explained the 9 mpg.

this has happened to me on many jeeps with the I6 - also do not assume plugs out of the box are gapped properly because my friend did and when i was doing my tune up he noticed how all of my champions were all over the place in terms of gap - i think this is b/c they are for many applications and need to be gapped accordingly - now his runs much better:chef:

Yeah they can burn a perfect circle in an injector nozzle. So if you drive anything with a Cummins in it don't worry about your spray holes not being good:yelclap:

My plug wires say Mopar on them...... Mopar Performance wires. Seem to run better than the stock wires, and cheaper to boot.
