Yup. I love my destination A/Ts. Good life and they are tough as hell. 10ply tread and 3ply walls. Did good on the trails at rausch

Is this referring to the tread separation problems? I remember the news all over that issue. I'd use em now if I needed tires. I normally just go for the one I can get the best price on though lol
Hi All, I have a quick question about my MAP sensor. Is it normal for it to read 17.4 in Hg at idle?
I've been having trouble with a rough idle and poor gas mileage with my '98 4.0 xj. It's been throwing the code p0171 and when I hooked up a scan gauge to it, the freeze frame data showed the MAP sensor reading 17.4 in Hg, which seems low to me. This has actually happened twice. Once it stalled out on me at a red light and it showed 15.7 in Hg.
So basically I'm asking if a MAP reading of 15-17 in Hg is normal, and if anyone has any other tips for helping me out with the p0171 code, that would be appreciated.
Thanks!

So, i read on the forum a lot about fog/extra driving lights. I also read that you don't necessarily want more light while driving in fog, but proper wattage and color. I know yellow light is better but does anyone have a recommendation on what type of fog lights i should look into?

I need a dropped pitman arm for my XJ.
I have a 4.5" lift.
I see prices ranging from $65 to $209. Does anyone have any preferences on Dropped Pitman Arms?

Not safely. The battery temperature sensor is used to control the rate of charging so that the battery doesn't explode (or just have significantly decreased life but that's not very exciting).
Lots of people recommend to me all sorts of crazy things without knowing what they do, too.
Reasons against one with a mostly stock setup are excessive bump steer. The track bar and drag link must be parallel. Non-parallel front end means more wear on the steering box and contribution to death wobble.
If you have a custom track bar and steering setup it's a different story, but stock track bar bracket or even one that is the same height you don't need it.
Drop pitman arm does not increase flex. What is the problem you are attempting to fix?
