Buddy> of all the vid's I've watched, this one is the VERY best on P0420!! GREAT job! Not sure what "Fire" is LOL! But I get the point. I'm headed to auto-parts store for laser thermometer for more testing. My 2001 Tundra 2WD with a 3.4L just threw the P0420. I'm DREADING the possibility that it's the CAT or BOTH CATs!! But it probably is, at least, one of them!!! I'll post again when I sort out my problem> it's pouring outside (Grass Valley) so I'll probably knock this out in a couple days.
I appreciate the support! Glad this video is helping, I wanted to cover all of the stuff that I learned from other videos and put it all into one. I'm stoked it's helping as much as it is! But for sure on the laser thermometer. I hope you don't have to replace both cats. I ended up having to after I tried the sensors. If you end up trying the 02 sensors first( if you haven't already) I would recommend staying away from the Bosch sensors. I had one fail within a year. I always love the updates of people fixing thier codes, so I'm looking forward to hearing back from you! Again I appreciate you and hope you get that Tundra running smooth again!🙏🏽🥷🏽🙏🏽🥷🏽🙏🏽
@@DrokuNinjahQ, will this still pass smog?
@@lilfaded....1400 Most definitely it will!
@@DrokuNinjah thank you
@lilfaded....1400 My Pleasure Man, hope you get your whip running smooth soon! And thank you for watching 🙏🏽🥷🏽
Dude 31549 gaskets I’ve been looking for weeks. I’ve been to Mechanic shops and nobody can tell me the right size. I think you just helped me.😂
I like the energy of this video I enjoyed. Also definitely helped with figuring out my 4runner, hardly anyone posts anything on how to repair them
Glad this video helped! And I appreciate you watching and commenting, hearing this type of feedback will have me posting everything I do to the 4runner! 🙏🏽🙌🏽🔥
Bro this is so helpful. getting ready to replace the full system this weekend
Sick! Glad this video helped. And hope you get your vehicle running smooth again! Sending you good vibes, thanks for watching!🥷🏽🙏🏽
@@DrokuNinjah actually follow up question for you - what bolts and washers did you use on the cats? I had M10 x 1.25’s but not sure if that’s right or what the correct length is
@kevinfrankenfeld2805 no problem, I actually forgot the exact ones I used. I know that I went to the hardware store and made sure the nuts were all metal lock nuts. I would recommend contacting your Toyota dealership to purchase some OEM nuts and bolts if you can make that happen. I wish I would have done that in the first place. Let me know if you have any other questions I'm more than happy to see if I can help!
Thanks, super helpful. I'm about to do this exact thing on my 1999 4runner with magniflow cats and loved watching this run through.
My pleasure! I'm stoked this has helped 🙌🏽 Thank you for watching My Guy🥷🏽
🔥nice work. Just ordered a Stainless Works Slim Body Hi-Flow Metal Matrix 100 Cell Converte RTCSLIM.
Will have it welded soon on my 96 limited. Paired with a stainless Gibson catback . 🔥🔥
That's SICK!!! Man whatever cat you are getting along with the cat back I haven't heard of before! You are putting us all on game 💯🥷🏽🙏🏽 Thanks for watching!
Good video. Ty. 99 t4r 320k here. Just got the 420 code. I'm here in the East bay. Just peeped your channel. See you be shredding kirkwood too. 🤙.
What's Gucci my Ninjah!? I hope this vid helps you get your 3rd "gem" running smooth again. And fasholly! You got a pass?👊🏾🏂🏽🥷🏽

Hell yeah bro thanks for the vid 🔥🔥🔥
My Pleasure! Glad it helped out. Thanks for the support!
I just double checked my 2000 SR5 3.4 V6. I only has one cat & 2 sensors
California!
@@dr.emilschaffhausen4683no California has 2 cats on 4runners
I checked the temp and both my cc is basically the same, maybe 10-15 degrees difference. Maybe the O2 sensor or is the temp check not definitive?
For sure! I would bet on the 02 sensor(s) thanks for watching!🙏🏽🥷🏽
I am having issues shimmying the front cat out now that it’s unbolted. Did you remove the center cross member trans support to get it out? This video is SUPER helpful btw
My pleasure on the video! Glad it's been helpful! For your issue getting the front cat out, I didn't have to remove anything but the rear cat as well(if you havent already done that). Let me know if you have any more questions, I'm always glad to help!
My first cat broke internally and it rattles like crazy. It fluctuates the rmps as well
Shoot, it's time to replace that when you can. I hope you get your vehicle running smooth again! Thanks for watching 🙏🏽🥷🏽
good video. im in south lake tahoe as well!
That's whats up! Thank you dawg!!!🙏🏾 where are you !? I'm by the Y!
@@DrokuNinjah over by bijou park!
That's SICK! we will probly see each other now soon! That's how this small world works. I appreciate you my Ninjah!
Are the magnaflow O2 sensor gaskets acceptable or would you recommend another kind?
Thanks for the vids, super helpful and straightforward.
The magnaflow o2 sensor gaskets are acceptable! They worked great. My pleasure on the video! I'm glad this has helped, thank you for the support 🙏🏽🥷🏽
Excellent Thank you.
My pleasure! Thank you for watching!🙌🏾🙏🏾🔥
Hell yeah bro
Why did you replace the back cat first? My 99 4runner has the same problem but I want to diagnose the front or back before doing anything myself. I had a shop work on it for two weeks and $1000 later and the issue wasn’t fixed. After doing my own research, I know it’s definitely a clogged or faulty cat.
Hi there! Apologies on the late reply. I replaced the rear cat first because that one usually goes out first (from what I have heard through research) but it was most definitely both cats that needed replacing because if one is going out, then most likely the other cat will be right behind it. I replaced the rear cat first ( I have another video of that) then the P0420 CODE came back after taking a trip to the bay area. If you have an infrared thermometer, then you can diagnose if your cat(s) are clogged by reading the front of the cats temp(while hot) and then the back of the cat. If the front of the cat is around 100 degrees hotter than the back, you most likely have a clogged cat. In my case, they were both going out, so I wish I would have done that in the first place. I know it's hard to determine if you need to replace both but if you end up solving your problem with just replacing one of the cats, that would be awesome! Apologies on the super long reply, but I hope this helps and I look forward to hearing if you get your issue resolved! Thank you for watching!!!🙏🏽🥷🏽🔥
Good video. Was your runner sluggish, hesitant and did not want to shift and getting stuck in 2k rpm’s? Thanks
Thanks for the support! To answer your question, yes my 4runner was a bit sluggish. But it didn't have any rpm issues. I hope this video helps you with your Vehicle!🙏🏽🥷🏽
I got the infamous p0420 code after replacing my o2 sensor 2 months ago. I'm not replacing that sensor again. I'm at 223K miles and I'm assuming it's time for new cats.
That's exactly what I had to do too! I thought it was just the sensors but ended up being the cats. That's our last resort foreal 😂 Hope you get it running 🔥🔥🔥 Thanks for watching!
Super helpful!
Kool!!! I'm glad to be helping others with this video, that's awesome and thank you for commenting and watching!!🙏🏾🔥
dope shoes brother, but even better video. Im about to take on this same issue myself. Im replacing my front cat converter because it rattles when i accelerate. Question!! Do I have to remove the rear cat if im just replacing the front cat??
Thank you! I appreciate your kindness 🙏🏽 and yes you do have to remove the rear cat to replace the front. You need a little wiggle room. Let me know if you have any more questions I'm more that glad to help!🔥🥷🏽
@@DrokuNinjah You're the man!! thanks for the quick reply. Removing the screws/bolts seems to be the biggest challenge considering they are old and rusted. How hard was that process for you and do you have any recommendations on how to overcome that obstacle.
I gotchu! I would saturate the sh*t out of the bolts with some PB blast then if you have one, torch them with some heat if they are difficult to remove with a your socket and breaker bar(s) 2 breaker bars help for removing the rear cat. And for the front cat you will need some extentions. I have a 10 inch extension I used to get to the nuts for the front cat.
The heat really helps if you have a torch. Or if you have to purchase one from the smoke shop they are pretty cheap. I would heat them up for 3-5 mins( depending on how stuck they are) and that really gets those things off! And safety glasses are a MUST🙏🏽🔥
do you have the part numbers for both cats? love the videos, thank you!
Yes I Do here they are! I purchased both cats at O'Reilly Autoparts!
Front Magnaflow Cat: Part#447192 , Price: $1,059.99 without tax
REAR Magnaflow Cat: Part#447225 , Price: $1,162.99 without tax.
(If you have a Commercial account with O'Reilly, you will get a HUGE discount on both of these. I purchased each for around 8 hundred a piece, I'll get you an exact price I paid when I find the Receipts 🙂) THANK YOU FOR WACTHING AND YOUR SUPPORT!🙏🏾🥷🏾🔥
@@DrokuNinjah those prices are ridiculous. take your chances with a pull. and unclog and catclean first.
Yes indeed! That most definitely happened first, thank you for watching!🙏🏽
What’s the difference between a cat from a auto parts store and a OEM. I might need one and he oem is over a grand.
The ones from the auto parts store can have a shorter lifespan and can possibly be made with lower quality precious metals inside the cat itself. I would recommend spending the extra dollar if you have it. You could be saving yourself time and money by getting OEM or going with the upgraded Magnaflow Cats. Thanks for watching and I hope this helps!🥷🏽🙏🏽
@@DrokuNinjah thanks a lot man.
My '99 only has one cat and it doesn't look like it's been modified from the Exhaust Manifold to where the flange is. AFTER the flange, it's been modded. ...I'm trying to figure out if it's the CA Trucks with 2 cats or all of them had 2 cats from the factory? I can't find ANY references to what they looked like stock.
That's an excellent question, and I will see if I can help answer that for you! I will reply back when I get some info. I would love to see pictures of what you have going on somehow. Feel free to email some pictures to me at Woodrowtaylor3@gmail.com if you would like! I'm interested in finding out the answer to your question as well.
Do you have a sticker under your hood that tells you the CARB compliance for your 4runner?
@@DrokuNinjah no… In 1999, I don’t think CARB was in place (maybe in CA?). It only became law in Colorado in 2021. if it makes any difference, The flange that attaches to my exhaust manifold has two holes then Runs down to a single cat. I don’t believe that has ever been replaced. After the cat, a new muffler was installed before I bought it. I have a carb compliant cat in hand. I may just have to break down and take it to Midas and have them cut and weld it in. Thanks for the response. 👍🏻
@@DrokuNinjah oh, and when I finish my workday, I’ll take some pictures and send them to your email.
@wildmustangart1577 I hope you get your 4runner running good! Sounds like your gonna get it fixed for sure. It's weird how it's different in every state for these cats. Let me know when you get it running smooth again!🥷🏽🙏🏽 I appreciate you.
Thank you
My Pleasure! Thank you as well for watching 🙏🏽🥷🏽
excellent video
Thank you I appreciate that! And thank you for watching 👍🏾🥷🏾🥷🏾🥷🏾🔥
@@DrokuNinjah Yeah man it’s one thing to worry about buying the parts but I love finding out ways to do it myself. really appreciate all the insight on the gasket stuff I’ve never tried it but now I feel confident to get into that as well. very insightful and its highly appreciated.
Word! Feels amazing that this video is helping so much! I am the same way as you with getting shit done myself. If we can do it and save some money, that's what I'm talking about! Again much love and appreciation 🔥🥷🏾🙏🏾
If you have any questions. Feel free to ask and I will do my best to answer them for you too
Did the PO420 code ever came back with both cats replaced?
What's up Jorge! Replacing Both cats solved the P0420 CODE for sure. About a year n a half later, the Bosch O2 sensor that I purchased( around the same time) failed and threw the P0420 CODE again. So I recommend staying away from the Bosch sensors if you can!🙏🏽🥷🏽
Will this pass emission n cali
Yes for sure It will 🙂
Thankx again
My code is asking for the front Cat. Do you recommend replacing both?
Oh for sure! If the front cat is going out, it's more than likely that both are on their way out. I figured out that both of mine needed replacing as well. I hope that helps and you end up getting your car running smooth again!🥷🏽🔥🙏🏽
I’m gettin this code and P1120 any thoughts? Truck has sudden deceleration when floored.
Hi there! Damn, feel your concern, these codes can be frustrating. I believe the P1120 code has something to do with your throttle sensor( or throttle body) not working correctly. You could try cleaning your throttle body thoroughly before anything else.
The throttle position sensor to be exact. I haven't fixed that code before but it could be just a dirty throttle body. Along with a faulty o2 sensor(s), getting a incorrect reading because of that. Not 100% positive but I am praying some of this info helps! 🙏🏽
If your vehicle is throwing multiple codes, it's probably a good time for a complete tune up🙂 I know I had to do the same!
TPS has been replaced with no luck. Next try replacing 02 and cleaning the throttle body?
Yes indeed I would go that route for sure. 👍🏽
So what was your thoughts on performance after the install?
The Engine runs AMAZING after I replaced Both Cats. Gas milage went way up and I noticed a little increase in power! Not a lot but I can definitely the difference!
Overall I'm SUPER STOKED after the install!! Thank you for commenting and watching!🙏🏾💎🔥
@@DrokuNinjah yeah this is my next venture on my rig. How much was the total cost? Also do you have a IG for your 4Runner?
@@gunsfishand4x4 apologies for the late reply! The total cost was a bit cheaper at O'Reilly Auto Parts( with a commercial account) so I got them both for around 8 hundred a piece, I will go through my receipts and get the exact number for you Dawg! And not an IG for the Runner yet! That's an amazing idea I have to start one! Thank you for that 🔥🙏🏾
@@gunsfishand4x4 my regular IG is @Droku_3 but you are influencing the 4runner page coming soon with a COMPLETE Raptor Liner paint job video! Thank you for watching as well🙏🏾🙏🏾🔥🥷🏾
What tools are parts are needed?
You will need a variety of 14mm sockets and wrenches, a variety of socket extensions( long and short). 22mm for the O2 sensor(s). Wire brushes for cleaning. The video shows what tools I used as well😁 Thank you for watching!
@@DrokuNinjah of course, thanks for putting out the content!!
@@DrokuNinjahare both o2 sensors the same part #? I have po420 as well. Gonna remove cats and clean them. Wondering if I should replace sensors while I’m at it
I believe the O2 sensors are different, and yes it would be a good idea to get some new ones. I would recommend not getting Bosch brand( I got one that failed prematurely) but also save your old ones in case for some reason they aren't bad, so you could still use them if needed. Thanks for watching and if you have any other questions I would love to hear them! Also would love to hear if this fixes your code 🙏🏽🥷🏽
My old bolts are fucked, rusted into one blob
Damn! I had the same issue on my last Truck and had to cut them off with a Grinder haha
Lol
Lmfao
Nice video but spare the language next time - thanks
