Where and how bad is the crack in the header? How close to the o2??
I'm thinking maaaaaybe with that crack your o2 thinks its running lean and sending more fuel causing it to f-up
Post up on naxja.org/forum in the OEM tech thread you'll definately get a answer there fairly quick

Look at your exhaust tip. If its sooty its running rich that code is usually a bad o2 causing a rich condition. If it was a injector the bad injector spark plug would be discolored. Like I said That hole might be sucking in air causing your o2 to think its lean therefore the computer will bump up fuel to compinsate for it. It can even need a tune up or have a bad coil. My money is on that header first if not that then one of the o2's. Or even a bad cat not Doing its job and the downstream o2 is getting a bad reading
Do any of you know where to grab one auto zone? or one I can borrow? Also not sure if this is the same thing but I did depressurize the fuel rail and then primed it and repeated to see if it was getting a little bit of pressure and seemed pretty consistent.

Borrowed from another thread exact size and placement
Spark plugs all looked ok I will double check after work to verify this because it was dark when I was doing this. The olny place that had discoloration was the coil had a small black spot and I cleaned that up with some sandpaper.

I don't know too much about diagnostics so you'll have better luck posting up on naxja.

I heard Glenn picked up a rig, If I remember correctly he snagged a XJ already modified a bit on a skyjacker lift. I may show but don't count on it. I had some plans though would like to get out there with a few of you all.

No prob, If you're in ABQ and want a hand with it let me know.

I'd say go down to 2nd or 4th St. Plenty of used tire joints, these guys sold me a set of 4 used crap 31s for $20. They lasted me an entire season. Then once you have the cash in hand for the tire setup you want go buy them.
Just my two cents...
