I don't remember the exact code number, but I had the same problem. It was a connection at the canister. Get under the Jeep and physically inspect the connections (Driver side, just behind passenger door, inside the frame rail). It will have obvious cracks. If there aren't any, follow the...

If it is the bearings, why not just replace those? It can be done without pulling the motor. I have the same issue with the bearings (2001 w/80K miles) but the previous owner used the Jeep to tow a lot. I use 20W-40 to keep it above zero and stopped using Fram oil filters. I don't think...

It's really hard to color-match black paint and not have it noticable. If you want everything to match, you'd be better off painting the whole truck. The charcoal and fading is the clearcoat rubbing off. If it's not too far gone, you could try and wet sand the Jeep, then buff it back to its...

Plastigauge is used to measure bearing clearances. You lay a small green strip on the rod journal and torque down the rod cap. Remove the cap and measure how much you smashed the green strip with the provided clearance ruler. You could do the same thing with a micrometer but those are a...

Technical Service Bulletin, I believe. You can check for them on autopedia.com

Are any of you guys losing coolant in addition to the misfire problem? I am having the same misfire problem (but scan say's it's on #6 cyl). I changed the plugs which helped for a while but the problem keeps happening. I know the '99 and up heads are notorious for cracking between the #3 and...

I'm having the exact same problems, and I can't offer any solutions. I have a 2001 4.0 with 80K miles. The oil press. gauge drops to zero when I come to a stop, then goes back up when I drive off. Tried a new oil pressure sensor with no change. Using heavier weight oil did prevent it from...

If you think it's water on the heater-ac blower unit, park the Jeep downhill next time it rains. If you don't get water, it's a pretty good bet you're right. I had the same problem and it turned out to be water falling right on the blower unit, running through the crappy seal, down the plastic...

Check the heater-AC blower housing seal. Rain water will run down the cowl rail and fall right on the housing and trickle into the Jeep via a crappy seal. Inside the Jeep, the water will run down the blower housing plastic and fall onto the passenger floor. Hope this helps.
