    Jeep TJ O2 Sensor Guide (Symptoms, Codes, Replacement & Fixes)

    I had that code with a new o2 sensor. Turned out to be a wiring issue. Make sure the plug is fully seated on the sensor to wiring harness. Inspect all pins for any damage/loosness. Then check the plug that goes to the engine wiring harness. Mine had a loose pin that wasn't making contact. Once...

    P0161 (4 new sensors) but no exhaust past 3 catalytic converters

    Hey, I have been chasing some CEL exhaust codes for a while. I had to replace the cats due to internal damage. Got a new front double pre cat from Eastern/Davico that bolted up good and I replaced the third cat with the same brand but for an XJ model as that one bolted straight up to the first...

    P0161 Code Won't Go Away

    Looking for help with similar issue: Replaced double precats with Eastern Standard/ Davico part (old ones were bad) and the 3rd cat I replaced with the same brand but for an XJ as it bolted right up to the first cat pipe. As of now I don’t have anything bolted up behind the 3rd cat (sounds...

    Steering Wheel Alignment

No matter how many times I get the wheel straight while parked (key in acc position) with drag link adjustments, as soon as I start driving it needs me to turn it to one o’clock to keep...

    Cat to Manifold Bolt Size / Length

    If I remember correctly, I used a 10mm 1.5 and “forced it” through. It had initial resistance and then went in after

    Best bolt sizes for manifold bolts?

    I tried an m10 x 1.5 and was only able to get a half turn with the hand before it stuck. Is that normal for that kind of nut to do that. Would I just switch to a socket and blast past that?

    Cat to Manifold Bolt Size / Length

    Does anyone know what size / thread count bolts to use for the OEM captive nuts part # 6506546AA. I have tried 10mm 1.5 pitch bolts & 3/8 course thread bolts. Both of them stop when I get the first turn in. The factory bolts part # 6505754AA are at least $30. There has to be some size / pattern...

    Looking for 3 bolt exhaust flange / pipe (off old cats) or aftermarket part number

    I've looked at every website. When I look at the bolt holes measurements (if provided in the Q/A section) none of them are the same as the size of the piece I have. I don't want to keep buying and returning items until I hopefully get what I want

    Looking for 3 bolt exhaust flange / pipe (off old cats) or aftermarket part number

    I am looking to see if anyone has any old catalytic converters with the 3 bolt pattern flange (see pic #1 circle) laying around that would be willing to cut off about 6 inches of pipe with the flange. I will pay for shipping and your time Or if you happen to know of an aftermarket piece that...

    How to flush the cooling system on your Jeep Wrangler TJ

    I wouldn't put the new radiator in and then do thermocure, as that would bring all the junk you cleaned out of the block into the new radiator. I would complete the flush with the old radiator and then install the new radiator. Just my thoughts

    P0420: Do I need a new catalytic converter?

    I looked on rock auto and saw some Davico pre cats and AP/Eastern 3rd cat (not familiar with the brands) for what looks to be a reasonable prices. Hoping for anyone with experience / insight with any of these brands to provide a stamp of approval. Hate to go through the trouble of buying /...

    P0420: Do I need a new catalytic converter?

    After getting a p1196 (and replacing the corresponding o2 sensor) and a repeated P0420 code, I decided to pull the cats off for further inspection. The front side on all was pristine. Unfortunately while having them off and shaking, I discovered a rattle inside. Upon further inspection with a...
