Check the ballast resistor. It's a big, white, ceramic resistor mounted to the driver-side fenderwall or firewall under the hood. It should NOT be cracked in 2 pieces... Resistance value should read approx 1.1 Ohms. A new one will run about 5 bucks if you need it. This circuit powers the...

Rev, There's supposed to be a sensor associated with the pressure bottle??? I guess It must've been ripped off somewhere along the line or during the collision! I replaced the old "baseball" resevoir a few years back with a "football" style one when I rebuilt the front end, but I just plugged...

Whoops, you're right, I meant to say "Command Trac"... I'm not sure why it would go off under load if it was an electrical issue though, except that the voltage is a bit higher under WOT, causing a voltage-sensitive short? Or the case torque is greater under WOT, causing in intermittent...

Well, I guess mine is an odd one... I have a '90 XJ W/ NP231, NHO motor, and Selec-Trac, and it has been doing virtually the exact OPPOSITE... Funny thing, I just figured I have a vacuum leak somewhere too... My system says "Part time" (meaning 4WD engaged) all the time, even of course when I...

Thanks for the comments guys. I had pretty much already decided upon option #2, but I was curious to see everybody else's solutions and reactions to the question. I have seen several studies which suggest that emmissions are often WORSE when a cat is installed though. Somebody on the JU site...

I am quite sure a flame-fest may ensue, but a couple of questions here regarding replacement or removal... Please don't start all green-vs-polluting BS here though, I understand that without a CAT the emmissions will be worse, IF the engine is running perfect mixture, the operating temps are in...

Just wanted to describe a problem I have noticed, and perhaps get some suggestions from you guys... I have heard various versions of things rather like this, so I will first proceed to describe the precise symptoms: '89 XJ 4.0l FI IL6 non-HO, stock everything, with LOADS of miles... Engine...

I once had a bad ballast resistor too... It was cracked all the way through. Normally it was touching all the way across the crack, so no problems. But, during serious vibration (like on a washboarded road) it would intermittently cutout. I figured that the resistor mustve shifted a bit...
