Of the o2 sensor voltage? Just idling? I could do that.

Question. With the durango steering box upgrade. Does it matter the engine size. I Know without snow plow package already

Would there be any adverse effects to running shocks for a 4 inch lift on 3 inches of lift? I can't afford the lift I want right now, but I just got my 31s mounted up and the 2 inch coil spacers are not enough, they're still rubbing a tiny bit. My thoughts were to go buy some 3 inch coils and new shocks for the time being. I already have an AAL which netted me about 2.5-3 inches in the rear.

Yup, once it warms up though. Here's an example of what you're looking for



That's not from a Jeep - because I'm lazy - but that demonstrates a mostly working cat. The signal from upstream represents the computer adjusting fuel to hit the 14.7:1 AFR. Obviously not a, er, fine work of art since it's constantly turning the amount of fuel up and down. Downstream should be a steady signal once warmed up as the catalytic converter smooths out all the crap. Compared to an XJ that graph looks like it's reading on the rich side with a higher downstream voltage. However, STFT and LTFT will tell you if it's constantly adding a ton of fuel or trying to lean it, or spazzing out and adjusting STFT wildly (points to a vac leak or some kind of other fail)

It will simply ride worse with the shocks extended 1" further than designed. Although your first sentence is simple but the situation is a little more complex... What's rubbing where? Additional lift won't do anything for control arm or fender rub at full lock. 31s fit very nicely on a 3" lift when done properly.

No. Just don't let them bottom out on up travel.

Dunno if this'll help much, I haven't had a chance to go outside and let the Jeep idle for 20 minutes or so. I did this earlier:

XJ Ask the Question Thread-ag2hyxp.png

Not the o2 sensor voltages, just the STFT @ LTFT %s. I did notice that the o2 sensor voltage (I believe it was upstream, [on second thought, it may have been both of them]) stuck at 1v for a bit after I turned the Jeep on. Is that normal or could it point to a wiring issue? I'll get more into this in the morning, but yeah. When I do do this is it okay if I drive around while I let it log? Shouldn't matter right?

Default HELP

So my Jeep's headlights will not come on. Normally I can shake the switch and they turn on. But as of yesterday they would not go on at all.
My dad has been trying to fix them and nothing is working!
He got new parts but not a new switch. He said when he got the headlights to work the taillights stopped working. I was wondering if anyone had this problem before, like is it the switch, or something else. I really need my car so please respond with anything helpful!!

She's rubbing on the fender a tiny bit under full lock, clears the control arm just fine. Went with some soft 8's too, so I've got some more back spacing there too, which may very well by part of the problem itself. I've always intended to trim the fenders, this just lights a little fire under that plan. We'll see how that works out with record lows approaching fast.
