FYI next time you might not want tj put anti sease on O2 sensors heat will transform antisease into cement

What timing! I just got an '01 TJ from another state that doesn't require emissions testing. He cut off all the cats, which I now have to replace. I'll definitely be referring back to this video!!

[@omargraziano3351]

Always so many comments about her looks...can we all just appreciate an awesome Jeep channel that feels way more genuine than others................

[@zr2zamboni906]

I scanned the comments and didn’t see one comment on looks. Maybe I missed it???

[@ememchi3717]

Thanks a million for this. My 06 Rubicon is doing the same thing but was throwing codes for a cylinder one misfire. After replacing what feels like everything it was still not running correctly. After weeks of trying to track down the issue and watching what seems like a hundred videos, yours was the first to show you actually driving the Jeep and exactly what it was doing. Also love seeing a fellow Jeep chick who works on her own ride! Thank you soooooo much!

[@jeepsandbeer3323]

Oh to own a TJ/LJ, We are averaging some type of breakdown every 3 weeks on our ‘98. But I’m never getting rid of her! I’m just glad my wife has the mechanical knowledge to keep her running!

[@freedomisforeveryone1776]

Great stuff! Always a fan when women can turn wrenches and aren't afraid to get dirty! Keep it coming guys 👍

[@jimcanz8696]

After Super Charging my TJ both pre Cats burned out and clogged the main. I pulled everything apart until lastly checking the exhaust. 28lbs of back pressure at idle. Definitely wiser now, but seems like it's more common especially with Turbo/Super charged 4.0L. Keep spreading the Good Word with the Videos. Wish you made the 3 years ago! Cheers!

[@bryansalazar8651]

I have a 2014 wrangler. Had the same issue I sped a lot o money in sensor, crankshaft, abs, etc. The real problem was the oil pump and oil sensors, besides I also had to change the ECM because it keep damaging the sensors. No problems since

[@floydstowe]

It's nice to see down to earth peaple who are not afraid to get their hands dirty like some other people on KZbin like lite something you are the real deal

[@joshuatyson3497]

you two are Awesome! keep it going and love the positive attitudes you guys brings to your channels

[@erickeasling4756]

You might want to check with a local shop but i'm almost certain you cant leave the exhaust dumping in front of the rear axle, it needs to be past the rear axle this is to keep exhaust fumes from coming back up inside the vehicle and casing you to pass out while driving. I could be wrong but worth a call happy jeeping:)

Good video. I found the bit about the T-case shift linkage/bracket very useful. Thank you for that.

[@vinces.2862]

2000 TJ 4.0 of mine same problem . Installed new stainless steel system. Runs like a champ. No more check engine light. Blown cats like yours. 230,000 miles on it.

[@jordandinoffria6514]

My TJ is in the shop right now due to the SAME issue. I'm in CALI too... decided to send a flomaster system over to Yuma, AZ. Hopefully my TJ will be back soon.

[@Deatomizer]

I finally get it! People who buy Jeeps are those who like to fix broken things. So many jeep fix it vids on KZbin has to mean something.

[@causeuncause4059]

I guess I got lucky I haven’t done anything to my Jeep except oil changes and spark plugs

[@brianshannon9996]

My 03 TJ has taught me so much in fixing it myself. even if it has had to sit on jack stands in the garage for a weekend!

"Modifying" and Fixing are 2 different things Clueless one !

[@jeromejccheung7032]

Had the same thing, but on a Grand Cherokee, but out in Cali, could not get an after market to change. Ours dealt with overheating issues. We ended up donating the Jeep to charity, since It cost more to replace the Cat then the value of the Jeep; at the dealer, where Cali only allowed it to be purchased and changed.

[@14Maxmom]

The auto TJs especially the 04-06 are pretty notorious for issues. Those who have the 42RLE know the struggle is real.

[@roderickclerk5904]

It’s mostly the computer in the 05 and 06

[@jaym4031]

You’re lucky you don’t live in a carb mandatory state like I do. I tried to order a non carb cat to be delivered to my state and summit said no. So I sent it to a friend in the next state over. About $1000 difference that I saved lol. Glad you got the Jeep running back to normal.

[@Tanner731]

some of us live in america. not communist republics

[@jaym4031]

T you can actually blame summit for that. They said they wouldn’t send me a non carb cat to my state regardless of what I was using it for. I told them I wanted it as a wall piece lol they still said no.

[@Tanner731]

@@jaym4031 Its not summits fault you live in a communist republic

[@jordandinoffria6514]

I am in CA.. I sent mine to YUMA, AZ lol

[@errhka]

Summit can get huge fines for sending you a non carb cat to California - that's why they don't ship it here. We have strict air regs for a reason - it sucks for car ownership but the laws do work. Air quality has improved tremendously (and continues to improve) since its implementation. When my dad grew up he said the air looked green all the time and most days in the summer you couldn't even safely breathe the air outside. Now most days are clear and we have good air quality most of the time. It's all about what you value more at the end of the day

[@andyli8595]

Am I the only one who saw the "unbroken foundation" on her shirt and looked it up ? it's definitely a pretty cool organization

[@tangledline]

When I got my TJ I built it up badass. Took months to get it the way I wanted...and then...the 4 door came out. Then everyone got one. I still have mine but it just sits there...I am waiting for a prosthetic arm from waving my other one off..lol. I am pro Hummer now. Owning an H1 and H2. The Jeep is used for the hunting lease...with AC..lol. Great job on yours!

[@bobatwater5912]

I have a TJ. Old school jeep. Did the same to mine. Great video to help me with things in the future.

[@leed7951]

Glad you got the jeep fixed. New tires nice. Great video thank you for sharing

[@Jeeptalkshow]

Double check this but one of the causes of a bad catalytic converter is the engine running too rich. This can be caused by a bad O2 sensor. I would recommend replacing the O2 sensors, and get the O2 sensors from a Jeep dealership, or a 100% Chrysler sensor. I've learned the hard way about using non-OEM sensors.

[@justinalexander4428]

thanks for the links...code just came on my daughters TJ with 200k miles. about to order

[@joshuafrahm8778]

I just bought an LJ this spring, about a month later I was getting the bad cat cel. After I bought the parts, it turned out that my front precat wasn't bolted to the manifold anymore. But I did the replacement anyways, Stainless cats, and a new stainless catback.

[@AndrewBrowner]

this was the first issue i had with my LJ when i bought it a few years ago, i did the budget fix and took it off then knocked all the cat material out with a hammer and pry bar until it was all straight through and fired er back on, no emissions tests where im from save 800$ and not have the same issue down the road

[@rediron44]

You lose power from an inline 6 that way. Those engines use backpressure from the cat

[@AndrewBrowner]

@@rediron44 thats been debunked so many times im not gonna argue about it, but even if it were true.. its a trail/daily driver not a drag jeep im okay losing a couple HP on the higher rpms to save the absurd amount they ask for cat pipes

[@hopalongjohnny9797]

Yep, my 2012 is doing this right now. Cam shaft sensors, $700 later and it’s still in the shop. Both cam sensors replaced and wiring harness pig tailed.

[@LordPhoenix140]

Be sure that when you replace the O2 sensors you only use NGK / NTK brand sensors. The TJ is extremely picky about certain parts like the O2 sensors and no other brand works well, not even name brands like Bosch. Definitely don't use over the counter parts store O2 sensors.

[@james94582]

Made this mistake twice before finding out it wasn't bad parts from the store, just picky LJ... But my XJ is just fine with Bosch O2 sensors... Never understood that...

[@tonyd3266]

often spraying electronic cleaner several times deeply into the tip of the o2 sensor will get you double life and will run like run for $10 in cleaner and $1 anti-seize.

[@Soothsayer-rs5nb]

TJ, the last real JEEP !

[@smokeGR14]

Bwahahahaha........

[@shadvan9494]

I would disagree. I have owned a 1995 YJ, a 2005 Tj, and 2015 JK. And grew up riding I’m my uncle CJ-3B every hunting season. Every generation has its high and low points. The JK is much better handeling and more comfortable on the highway, however the 3.8L v6 in the early JK is a. Piece of junk. the old L6 was much more reliable. The new 3.6l v6 is much better for reliability, but still doesn’t have the off idle torque of the inline 6. And don’t forget the YJ had those awful square head lights. For years I heard real Jeeps have round headlights. Like I said every generation has its high and low points

[@JeepTJWheelin]

@@shadvan9494 I had an '08 JK X with that lousy 3.8 mini van engine. I now have an '05 TJ Rocky Mtn and this is by far the best vehicle I've owned. As long as you get one with the 4.0L I6 with a Dana 44, 3.73 or 4.10 gears, you will have a very good TJ. In my humble opinion, these are the best Jeeps, second only to maybe a CJ-7. The low end torque is outstanding on these TJ's. They are quick especially if you have 32 x 11.5 15 tires. The bfg ko2 are great tires for these rigs. I'm sure the 3.6L are good but for me, there's nothing like a 4.0L. This TJ handles much better on and off road than my old JK. Of course, I put Rancho RS5000X shocks with a Curry Link tie rod and drag link that has this TJ handling extremely well.

[@rediron44]

Total ignorance

[@shadvan9494]

@@JeepTJWheelin I loved my 05 TJ Rubicon. it was a great jeep. and I agree with you on the 4.0L L6. that was a great engine. the off idle torque was unmatched. the 3.6L v6 in my JK is not bad but it is not a good as the old 4.0L. I ran the BFG 32x11.5 KO2 on my TJ as well. great tire. My JK came with the BFG Mud Terrain KM 255/75R17. they were loud and they wander a bit at highway speed. I switched them out to BFG AT 285/70 KO2. (the metric equivalent of the 33 x 11.5) and they have been great! I am looking at swapping my factory shocks for the Old Man Emu's. on a side note, FCA is working on a new inline 6 with a turbo. From what I have heard it is based on the same design as the current 2.4L turbo 4 cylinder and will be able to work with the same electric drive systems available in the new Wrangler JL 4XE version that are coming next year. there is also a rumor that the 392 hemi V8 will coming in the new JL as well. also the new 3.0L diesel in the new JL is an absolute beast off road. but the price tag on a new wrangler with a diesel is painful.

[@KevinFlynn1967]

Great job guys! Love it when a plan comes together. Huge fan of the channel!

[@zukesrubicon1130]

I found the thicker flanges on the Flow Master mini-cats required longer bolts than the original. A friend of mine replaced the captured nuts with regular nuts, washers and longer bolts. Without the longer bolts, the flanges just would not stay tight.

[@old_channel1]

It is a good idea to clean the sensors using something Lucas Fuel Treatment now that they are out. Takes a full day however to soak it, clean it, let it dry and install.

[@EigerSummitOffroad]

Check the catalytic converter and don't drive it at all. get it towed to an auto shop. My 91 XJ Laredo did the exact same thing and on the way to driving it to the garage the engine blew. silver metal rod pieces everywhere. Hope it all works out! To be a bit more clear, the catalytic converter had fail. I couldn't get over 30mph like yours. not understanding what was happening I ignorantly thought I could get it to a mechanic. edit.lol. i hadnt watched yet and wanted to get that info asap to you guys. You got it covered :)

[@appathejku5848]

Looks like those old cats used all nine of their lives. 'Meow', it's good that you replaced the exhaust.

[@NH2112]

I would have put new O2 sensors in as well, another $125 or so is worth not having to pull the old sensors with the exhaust in place later on.

[@charlesaceasarii1797]

Great video. I changed out my cat last year on my 06 Tj, had the same problem.I had to order the cat and it took 2 weeks so in the meantime I removed the 02 sensor that hooked into the cat, sprayed seafoam inside and let it heat soak. It worked like a charm. I still replaced the cat though as it was already ordered. :)

Simple quick test is to pull out the upstream oxygen sensor and drive the jeep. It will be louder but you should have regained power.

[@ebikeengineer]

At 0:28 you can see the CEL start to flash. When the CEL is flashing - shut the engine down immediately or risk major engine dammage.

like watching y'all tackle these little projects. Y'all videos give me the confidence to tackle things i would normally pay someone else to do. like the garage too.

On a side note, I grew up in the area y'all just moved to...it's beautiful down there but HOT

[@tonyd3266]

btw - I would replace the muffler too, those cat parts go there next. banging it with a rubber mallet and listen to the rattle. ALSO - that cat core is worth $$$. maybe $75-200 - dont throw away your exhaust - look online for place that buys them. they are filled with Platinum.

[@rickjameschannell4565]

I had a bad O2 sensor and found out if not changed it could foul up your catalytic converter due to the computer sending too much fuel cause the o2 sensor sending false readings. I would change o2 sensor so the new catalytic converter doesn't get loaded up from running rich.

[@thedeathwobblechannel6539]

change t case oil too. i put 2 quarts of Lucas atf and the old 1/2 pint LMAO of coffee was replaced. new oil makes it shift so easy.

[@beefpiston]

Thank you so much for this video, y'all have definitely earned my subscription. I bought my first 97 TJ 3 months ago and about a week later it started doing the exact same thing. I know all vehicles have cats and this could happen to any of my other vehicles, but since I'm new to the jeep game I was completely lost.

[@anubis8680]

had a Chevy S10 that did that wouldn't touch 3K and it held at a certain speed. Turned out to be a corrupted section of wire somewhere under the hood so it wasn't getting the right voltage. So the ECU went into Limp mode. Forget what wire; start running continuity tests with that cool multi-meter that you bought once and tossed into the toolbox and probably never used : )

[@dalephillips8250]

Crazy to replace Cats at 100K. I drove my 2005 Dodge Ram 260K and never replaced the Cat. I've seen Crown Vic, Grand Marquis & Lincoln town cars with 500K and had not replaced Cats. But if it needs it I guess you have to do it.

When you got that exhaust out of there using just a ratchet with extension, i was here shouting at my laptop. I had to pull mine a month or two back to get the oil pan off, and I ended up taking the entire driver fender off to get to the damn flange bolts! I'm almost happy that you couldn't get them back on so easy. :P (Sorry).

[@saaaron5213]

If you are stuck far from home and you know you have a clogged cat, or you wanted to 100% confirm the problem before replacing it, you can always use a cordless drill to give her a tracheotomy. Lol

[@grampawwillie1665]

we had that happen on a Patriot. It needed a new throttle body.

[@shroom903]

Is your check engine light still on. One main cause of catylitic converter failure is faulty o2 sensor. You better check it now before you burn up your new cats. If it's reads wrong, it could either run lean or rich. I'm guessing rich since your cat is gone. The unburned fuel collects in the cat and ignites causing it to get hot and brittle, eventually falling apart.

Let me guess - P0032, P0038, P0052, and P0058 codes. I just did the same thing for the same reason over the Independence Day weekend. I replaced the O2 sensors as well. And installed a new oil pan to replace the old one that was almost completely rusted through. I might have the only 255K 4.0l with no leaks from the rear main (I did have a new seal in case the oil underneath was from that and not seeping from the pan.)

[@SLICKW1993]

These Jeep’s all have similar problems. Cats, transmission solenoid and plastic radiator that likes to crack. That’s the problems I’ve had with my LJ over 9 years at 130K miles.

[@matthewglaze5398]

Check engine light is flashing so my guess would be crank or cam position sensor.

I want to buy one of these, and a guy has one for sale a few blocks away. I just see so many problems with them, not sure I want to bother. I have a 4x4 pickup, a Lexus, a Porsche, a Harley, and a BMW R1250GSA, but I kind of wanted a Jeep to ride around with.

[@robertcarender2907]

The same thing happened to my 09 JK Wrangler Cadillac converter stopped up. I lost power. You need to check your exhaust headers. Because it cost mine to crack and Brake bolts off exhaust header. My Cadillac converter fell apart to inside also. I think I'm going to have to change the O2 sensor. Because the engine light come back on still running a little rough. I think the Cadillac converter when it fell apart got inside your two sensors.

[@thatguy7085]

Exhaust gas leaking anywhere near the transmission can screw up the transmissions fluid viscosity… that will cause the vehicle to stop shifting suddenly when it gets warm.
