O2 sensors are new. Smoke tested the exhaust, no leaks. Cat has less than 5000 miles on it. No CELs. AFR's via my wideband are spot on. Plugs are new and look ok.

The mechanics want me to throw a new cat on there, so I'll likely build a new rear exhaust while I'm at it. The 3" is a little overkill for the stock 4.0L.

I just want to drive this POS...
When my 91 XJ had high NOx it was bad catalytic converter.

Yeah that seems like the next logical step. It's just weird though that it has low miles and physically looks ok?

Once I replaced it passed with flying colors.

Re: The Colorado BS thread

As you probably know, NOx is caused mainly by excessive combustion temps. What did your HC read? If you have some headroom, maybe you should fatten up the mixture a bit if you can get away with it or dial back the advance.

Re: The Colorado BS thread

I'm super happy with it, and maybe even more happy to finally be done with this phase of the garage improvement. The only big thing I have left to do is either insulate the roof itself or cap the ceiling and insulate that, either route is going to be further down the road as I need to take a break from it all. There will still be little things here and there, adding some shelves and hanging a few more lights, but I'm done with having to move the entire garage around to do stuff.

Re: The Colorado BS thread

While finishing the work around the front end I keep looking at the Radius arm front and think I want to upgrade it just to do it since I could re use the old rear lowers for front and I have extra joints . The things I have been mostly looking at is upper link placement for a triangulated set up I like the idea of making the upper links same length as lower to keep my pinion pointed at the case output , but that puts the links in the way and would limit the angle I could set them at , So completely ditching the idea of eaual length uppers to lowers and mouting the uppers back at the crossmember I am toying with mounting them on the bottom of the unirail just back where they start to curve up this should allow me at least 75% of the lowers and would favor maintaining caster angle during cycle rather than pinion angle ...I do not want to do any work beyond the Radius arms already there for anything that retains a panhard.

Re: The Colorado BS thread

Mile Hi Jeep or one of the mostly Barbie Jeep clubs must be having a run for New Years at SlaughterHouse since there was a huge group of Wimmenz Jeeps staged at Loaf&Jug ... The JK crowd are the hard parkers of the off road scene ...lol

Blending thick sections of steel together to look like it was one formed piece sure does eat up the old mig wire .

Re: The Colorado BS thread

Sadly(?) I am aware of such cure... I have an idea spinning about in my tiny little mind.
