I am glad I found your video. I spent around $100.00 on cleaners that you add to the fuel. But not one of them work. I did what you showed in your video and it worked. Thank you.
Thanks for taking the time to make this video. To be honest I didn’t think it was going to work, for a money I thought you were about to blow up your Catalytic converter and your muffler but I’m glad that you didn’t for you and because I have the same problem in my truck
@@gerardoespinoza7202 this is simply a cleaner there is no way this would harm the exhaust. Some people go as far as removing the CAT and soaking it in soapy water to clean it. In this case, once you use the sea foam, wait a few minutes for it to soak then turn the car on to blow out the sea-foam and the heat will completely dry out anything inside the exhaust system.

You all need to understand that each cat converter is different and depending on how old it is and how much dirt build up inside especially if there is engine oil leaks definitely need new converter. I would say this method he showing would work of the issue at the early stages and not much crap build up inside the cat converter
Have same code 20 and 30 . I did the spark plug fouler.. the cleaners in the tank . My.. 2008 tundra 200 000 miles low pressure wen I press the gass. .I'll definitely try this today. Thanks
@@marvxc18 the light will not go away immediately. After changing the cat, you have to drive a couple hundred miles or several cycles before the computer realizes the problem no longer exists and turns off the light. If you’ve already done that, then maybe you have to replace the oxygen sensors. There are videos on TH-cam that show you how to test an oxygen sensor. Unfortunately I don’t have a video like that.
I had a rough idle caused by opd spark plugs my V6 has 2 cats, current codes are P0300, P0420, P0430. New pligs so runs smoother hoping codes clear in next 100 miles if not I guess I'm trying this in each exhaust half
I've been dealing with the same issue on a 2015 Volvo S60. The P0420 code keeps turning on and off. I'm going to see if I can do this and save the small fortune. Thanks.
@@onlyletisrickolous it may work for you or maybe it won’t but for a $10 investment it is definitely worth a try. Please keep me posted on that. Also, even if it helps keep your check in engine light out long enough to pass inspection. It’s a win.
@@sapphirejan2040 I did not get to try this method. I had already tried Cata-Clean the month before. It did clean the cat very well and improved the gas mileage but with these additives you have to try them very far apart. Especially with some of the solvents in some that can react with alkalines in others. My case was unique because the SUV I bought had sat for a year while waiting for an engine from Ford. So the cat had to be changed out as well as the sensors. The tactic in this video seems solid and if I had not tried the other cleaner I would have done this. Seafoam products have been a go-to over the years.
I started with. 420 code replaced the o2 sensor then got a air fuel ratio code & it’s been like 3 years I can’t get rid of the code definitely giving this a try ‼️
Has the light come back on, I've tried Catoclean, works and light went off, then exhaust leak gotten worse and it came back on after time. So I don't know if small exhaust leak, haven't looked as I can't anymore from pain on my Honda 2.4L these all seem to get the same code from chevy to Honda to Kia and others that has 2.4 engine, not in my old 1999 Plymouth voyager, clogged instantly at 170K and never burned oil ever, still in yard with clean oil at 200K , off road from 2011, need to scrap it
Light never came back on. I made a separate video showing the Scan Tool read after several hundred miles to show that there were no pending or permanent codes. Please see my other videos if interested in seeing that one.
My 2015 HONDA fit same thing the Engine light went on and i stop at the O'reilly for free scan . showing p0420 as everyone in here. i clear the code and put STP treatment in the fuel tank at the gas station aslo fill it full. i wonder will it hard to do the 2015 honda fit. thanks.
My buddy's muffler shop told him to do the same thing. But my buddy is hardheaded and is going to a mechanic. Just to pay someone money to tell him to buy a new Cat and install it. It's probably gonna cost him $1,100.😢
@@fordresurrectionest9556 wow I’m sorry to hear that. I’m not saying it’s a guaranteed fix, this method may not work for everyone, but for a small $10 investment it’s worth a shot before spending a small fortune.
If you really cannnot remove the upstream sensor than you can try the other methods, but it won’t be as effective. Definitely worth a shot. Atleast you’re trying something.
just did this on my 87 ford f150 with the 5.0L. smokes like a banshee for 15 minutes after starting it back up....white cloud. hopefully this did the trick. I don't have a code for this (ODB1)...the O2 sensor is new (bosch) and was black as soot.
I have a 2013 Acura TL SH-AWD V6 can I try this without removing anything? Really on a budget I have a below threshold on bank 2 code.. I’m getting really high $$ estimates hoping I can get some luck to buy me a little time until repairs. My car idles really rough, losing power, & a shaky when I’m at a stop
@@brittneywilliams8851 hi, thanks for watching my video. you absolutely can. It’s not a guaranteed to fix your problem but it’s definitely worth a shot and you run no risk of hurting anything. If you read the comments, you’ll see it has worked for quite a few people. Let us know how it works out for you.
NICE. I have a 2013 Dodge Journey 3.6 it has a catalytic converter in the front and another one under the middle of the car. do you think it will not hurt the under neath converter 02 sensors???
@@NewBayERA it will not hurt the sensors. In my video I only removed the top sensor (upstream sensor) just to have direct access to spray the CAT. I did not remove the bottom one (downstream sensor) It did not harm the sensor.
Seafoam actually works in the oil, gas, ( & obviously in the exhaust too) says so right on the can.... Seafoam is great stuff. I had old gas in my Harley. I drained as much out of the tank as I could, by siphoning, since I didn't want to remove the tank. I was told by Seafoam to add a can of Seafoam to the tank with a gallon of fresh gas.... It worked great, cleaned up the fuel pump, injectors, hoses & lines, & any residual old gas & varnish!
I’m a firm believer in the seafoam I use it in every thing to fuel oil the booster line. I also have had that rotten egg smell in my cat but did a few treatment of it and has gone a way. I will find out today or tomorrow if it really works after having my emissions done.
Great it is the first video that really solves the issue. I just have a question: In the monitors (OBD II) does it show as complete? The issue I have is that It does not present a code but in the monitors shows the catalyst as Incomplete. and therefore it does not pass smog. So in you experiment, was the catalyst shown as complete?
I use the Walmart super-tech brand with the Acetone it does a much job than sea-foam and it’s much cheaper Roughly three bucks a can compared to almost $9 bucks for sea-foam it’s more of a lubricant the Acetone is the primary ingredient in the supertech throttle body cleaner and I have is much effective in desolving carbon buildup and varnish good luck 👍🏽🍀
The carburator cleaner or parts cleaner? Man this would be my last option, i ve tried everything even removed it and soaked it over night! Def dont want to pay the $2300 for a new cat😩
I have two Cats (V6) and 4 sensors! OBDII indicates P0430 (Bank 2).. should I work on Bank 2 and ignore Bank 1? By the way, if this works, it will save me $1,800. Thanks.
Also, just curious if your spraying right into the cat and not the motor I would think it doesn't have to be seafoam..it could be brake clean, carb cleaner, etc
Brake clean or carb clean is completely different and fairly quickly evaporates so it would do no good. Seafoam sits there and penetrates the buildup in the cat.
When you are spraying the seafoam into the air sensor slot, does that clean all the banks of the catalytic converter. My air sensor is under my truck. Thanks.
@@brownyes6211 It will clean whatever cat sits below that 02 sensor. If you have 2 banks you will need to remove and clean each cat through the top of both upstream sensors.
@@brownyes6211 remember that it has to go through the hole of the upstream sensor not the downstream sensor. The upstream sensor usually sits below the exhaust manifold just before the CAT
Another proven and great way to do this is, let the tank get a hair below 1/4 , pour in 1 gallon of laquer thinner and run on the highway at speed 30 to 60 mins, re fuel. The engine 420 code will go away and the sensor and cat will be removed of slight impurities
Be careful where you put dielectric grease or any kind...because the O2SEN needs ambient air to function. Air is drawn in through the wire harness for comparison to oxygen in the exhaust.......I'm not sure if it applies to A/F SENSORS....BUT IT DOES WITH. ZIRCONIA SENSORS
yes soo true, it go into the exhaust. I was going to do the same thing before I just bought fuel injector cleaner and did a fill up. Drove it home says 10 miles, and the next morning started the car and the check engine light with that code was remove. But if that hadnt worked, yes i woukd bring out the 02 sensors and clean and clean where all opening and surrounding area too. We think so much carbon burn up cause all alot of error codes
@@danielkalanyos9130 you should definitely give it a shot. You’ve got nothing to lose and everything to gain. If you’re not successful at correcting your P0420 with this, you’ll at-least help improve its performance by cleaning the cat. Maybe you’ll get both !! Keep us posted. PS be sure that engine is cool before starting this job.
@@robertroman55 if you have a bank 2, that’s a separate upstream oxygen sensor. Bank 1 is passenger side of vehicle or right side of engine. Bank 2 is left side of engine or driver side. For each bank, there are two separate oxygen sensors, bank 1 upstream and bank 1 downstream, then bank 2 upstream and bank 2 downstream. So if your code is reading bank 2, then it would be the upstream oxygen sensor on the left side or driver side of the engine that you would have to remove and spray. But it would not hurt to do both bank one and bank two. I hope this makes sense and I’m not confusing you more.
I find any Chevy product to be the worst. Absolutely worse for there sensor issues and going off with codes. How do I know? I owned to many. No more and it’s been 10 years and never had an issue with other brands
I tried this with a bottle of carb cleaner and the short red straw fell into the hole. Took off the bolts on the cat and now i cant find the straw. Weird.
I just bought a 2010 nissan rouge and the service engine light is on and this is one of codes that came up. I ended up buying the Rislone cat complete system cleaner but haven’t used it yet. Unsure if I should try the Seafoam spray instead?
Honestly it can’t hurt to do both. The Seafoam and the Rislone. By placing the Rislone in the gas tank you’re helping to clean the entire system. And by spraying the Seafoam directly into the Cat, you’re helping to clear up some of that carbon buildup. Again keep in mind that this is not a guaranteed fix for your code. It all depends on how bad the cat actually is. It may or may not work. For the price, it’s definitely worth a shot. Worst case scenario, you’ll help improve gas mileage and acceleration. If you can even call that a worst case scenario. Ha ha. Let us know how it turns out.
@@crushrreviews no the steering wheel doesn’t shake🙏 The car shakes just a bit time to time like when I’m stopped at a traffic light or something but other than no weird noises coming from the engine or when I start the car.
One of my previous high mileage cars has this code occasionally. I reset the code then notice that the code doesn't return until after refueling at Costco Wholesale gas station.
Spray into the opening after removing the upstream sensor, let it soak for about 20 minutes, then idle the car for about 10 minutes or so until the smoke dissipates. When smoking out the exhaust, idle the car at about 1500 RPM. It will help heat up the exhaust and burn out the residual Seafoam.
did the P0420 code leave ? why didn't you show that . Without that information I could still fail inspection. i say that because the check engine light could leave but the code will still be in the CPU or not Sync up, it will still have an X and not a check Mark next to the cal code for newer cars . wish you would have shown that . needed to see that before i do a 4 day test . other then that good Vid
@@KESSTHEMC you’re right ! I should have done the re-scan afterwards. My code was gone because it was a pending code, it had not become a permanent DTC yet. Unfortunately Permanent DTCs cannot be cleared with an ordinary OBD scanner. If your code is permanent, the problem would have to be corrected and the car has to go through about 10 normal drive cycles before the ECM clears the permanent code automatically.
do you have to reset the thing with that device before you test drive it ) or will engine light eventually go off by itself after you drive +/- 100 miles ?
You can reset it if you want to, but the computer will erase the code and turn off the light on its own after a few drive cycles where the problem is not present
@@PathToPeaceMoe that would be a code for bank 2. Definitely worth a try. if it persists after the cleaning, try replacing the upstream sensor on that bank
I got a 2014 Honda accord sport with the P0420 error code. I am going to replace the censors AND I am going to use thi magic Seafoam. Not idea this was around. Thanks for this video. I just subscribed
@@crushrreviews thanks…. Well, I just bought them all. Trying the foam now. It is fine, compared with the ripoff from Honda, $300 is nothing from autozone. My motor vehicle inspection is due next month. Thanks a lot for your help. Without you, I wouldn’t have saved soooo much
Crushr how often do they have you check smog in your state? Do you have to have all your readiness monitors completed to pass smog? I am glad you got around putting on a new cat. I just replaced mine. You saved a lot of money.
@@dogsplantscarsneatstuff176 hi, and thanx for taking the time to watch my video. I really appreciate that. To answer your question, In my state “NY” we’re required to pass a smog test every 12 months. We’re allowed the following, up to two monitors to be in a "not ready" state for 1996 through 2000 vehicles and one monitor "not ready" for 2001 or newer model year vehicles. I’ve been good so far. Check engine light still off with approximately 201,550 miles on the odometer as of today. Now a question for you, was your CAT replacement expensive? Did you do it yourself? Just want to know for myself if and when the time comes for me to replace mine. Looks like a pretty easy DIY project.
@@crushrreviews At 240K miles my cat finally gave up. I may try soaking my old cat in a solution like lacquer thinner. Before I talk about the putting on of a converter let me say how disappointed I am in the warranty of the new cats: 25K! The bogus 50K warranty is only for the outside of the cat. In a state like NY where you lay down a lot of salt I be enforcing the warranty may be next to impossible. I did the cat myself but was surprised at some of the things I had to go to. All catalytic converters are expensive as you well know so I got mine off of Rockauto. I buy a lot of stuff off of them and have had few troubles although they are not known for being great if things go south with a bad part. Here is the big education factor: If you get just a cat converter those old pipe expanders that you can borrow from Autozone or OreillyAuto such as www.oreillyauto.com/detail/c/evertough/rental-tools-evertough-1-1-2-to-2-7-16-inch-tailpipe-expander/ren1/67096/v/a/2625/automotive-car-2002-buick-lesabre?q=exhaust+pipe+expander&pos=7 are not usually success in expanding exhaust pipe to slide your cat into. This one works on std. 16 gauge exhaust pipe with my Ryobi std. impact gun: www.amazon.com/Astro-Pneumatic-Tool-78835-Stretcher/dp/B01JBICBJ4?th=1. It is $100 to $130 on amazon. Harbor freight has one for $150. The original Lisle tool sells for about $215. If you do a second one this tool will pay for itself in money and frustration. I used band clamps to connect it the new pipe. Although I originally bought std exhaust clamps they crumple the connections and make it more work to remove components in the future. I went whole hog and bought the catalytic converter, resonator line, and the muffler all new. In Calif. I had the choice of buying a new Magnaflow cat from Autozone or OreillyAuto for $1300 off the shelf. I chose the Rockauto's AP/Eastern for $540. I got mine without the resonator since it was cheaper to get the separate resonator with the extended exhaust and the muffler from OreillyAuto with their 20% off sale. The resonator assembly and muffler were another $290. I got the 2" and 2.5" in band clamps from amazon at half the price of the auto parts houses: $8 vs. $15. I have 4 six inch high railroad ties that I drove the car up on securely. I couldn't use my creeper since I am a overweight. Not a great idea. I also used permatex ultra red to connect the exhaust bands to the pipe. Jack stands would have been better. Although the resonator and the muffler were from Walker they look so much wimpier than the OEM original. Here is the only nice thing I can say. The last two smogs (two years apart as per Calif. smog check) I had to drive 250 miles to get my catalyst monitor to complete. With the new Eastern cat I drove less than 40 miles to get all of them except my evap monitor which we don't have to complete in Calif. Although I could have welded the joints I wanted to make sure everything worked before I finalized the deal. Hope this helps. i am thinking about getting a home lift for my cars since the 6 inches was close for my car. People report sales of Quickjacks on slickdeals if you are interested. Hope this helps.
PS with band clamps you want to check them for tightness after a short time due to the expansion and contraction of metals and the possible leakage of exhaust pipes. Hope I didn't miss anything. Feel free to ask more questions.
@@dogsplantscarsneatstuff176I actually own a Quickjack 5000, I honestly LOVE IT !! It has made working on my cars sooo much easier. Yes it’s up there in price, but it’s worth every dime. It’s made by Bendpak which has been around for decades and has been tested by the folks at Quickjack to show it far exceeds the rated capacity. I use mine without worries and no need for jack stands. I recently saw that VEVOR makes one also, but honestly it looks scary to me. I don’t think I could trust the VEVOR one. Maybe I’m wrong. But I’ll never know. The Quickjack goes on sale during FEMA and also COSTCO has good prices on it from time to time. They all ship from Quickjack anyway. I highly recommend. The Quickjack. I’ve owned it a few years now and it’s flawless. Maybe I’ll do a video on it for my subscribers. Haven’t done one already because there’s tons of videos on it.
That one is a little tougher to do because of how the pipe bends after the O2 sensor. But with a long enough spray stray you might be able to get at it. Just be sure that you swirl the straw around as best you can to get at most of the cat. I believe you’d have to go from under the car for that one.
umm aren't you supposed to put this stuff directly into the throttle body intake, crank case and gas tank? this stuff is designed to clean the topside of your engine.
I did the same process, but my car hasn’t stopped smoking after running it idle for 20 minutes and after driving it around. Should I drive it more or anything else you recommend?
On my 03 Camry, it started with the P0420 code. I replaced the cat and code cleared and the stupid code P0141 appears, so finally I replaced the pigtail and all good. Now the stupid P0420 code is back and I tried the sea foam. What the hell is going on??
@@crushrreviews I replaced the downstream one 2 times and when I finally replaced the pigtail the code P0141,cleared but now the code P0420 came back. I was thinking of replacing the upstream sensor since it’s on the cat itself.
could be an 02 sensor, maybe an exhaust leak before the back o2 sensor, I've also heard rumors that the mass airflow sensor/fuel pump or even gas cap can cause the code
@@toontoonjr. I wouldn’t recommend that since you have to spray nearly an entire can through there. Also you want to spray that directly onto the CAT for best effectiveness.

Lucked in that the smoke didn't blow towards any of my distant neighbours whilst in my 07 Corolla and to be safe I was wearing a half mask respirator that would filter any of those white fumes. So far so good. Thanks!

You all need to understand that each cat converter is different and depending on how old it is and how much dirt build up inside especially if there is engine oil leaks definitely need new converter. I would say this method he showing would work of the issue at the early stages and not much crap build up inside the cat converter
Have same code 20 and 30 . I did the spark plug fouler.. the cleaners in the tank . My.. 2008 tundra 200 000 miles low pressure wen I press the gass. .I'll definitely try this today. Thanks
Did it work?
That sounds like a throttle body needs replaced bro
I followed ur instruction perfect , now I have 2 codes instead of one
😂
What is the other code?
You probably switched on the ignition while the air fuel sensor was disconnected, thus creating a fault and a dtc code.
Yourr lime green gloves provide High Contrast with the parts you're working on!! 👍
That's a great video and very well explained, thank you very much
This definitely worked on my 2017 Honda Accord thanks 🙏🏾
That’s awesome to hear ! Thanks for coming back and sharing your results. Please stay subscribed. Maybe I can help with other repairs.
Did you replace any part? My 2016 Honda accord has the P0420 code I replaced the catalytic converter and it still has the light on.
@@marvxc18 the light will not go away immediately. After changing the cat, you have to drive a couple hundred miles or several cycles before the computer realizes the problem no longer exists and turns off the light. If you’ve already done that, then maybe you have to replace the oxygen sensors. There are videos on TH-cam that show you how to test an oxygen sensor. Unfortunately I don’t have a video like that.
Excellent video sr. I’m working on.
Thank you. 🎉🎉🎉
Same issue with my daughters car, I will def try this. Thanks
I had a rough idle caused by opd spark plugs my V6 has 2 cats, current codes are P0300, P0420, P0430. New pligs so runs smoother hoping codes clear in next 100 miles if not I guess I'm trying this in each exhaust half
If nothing else works, it is my understanding that spacers / defoulers on downstream o2 will resolve and get you to pass.
I've been dealing with the same issue on a 2015 Volvo S60. The P0420 code keeps turning on and off. I'm going to see if I can do this and save the small fortune. Thanks.
@fengetaset9488 Did it work?
I am also wondering if it worked? I have the same problem with my 2015 xc60
Can’t hear well with the bell in background
Very interesting. I am currently dealing with a cat code that is keeping me from passing emissions. May give this a shot.
@@onlyletisrickolous it may work for you or maybe it won’t but for a $10 investment it is definitely worth a try. Please keep me posted on that. Also, even if it helps keep your check in engine light out long enough to pass inspection. It’s a win.
Just curious how did it go? Did it work for you?
@@sapphirejan2040 I did not get to try this method. I had already tried Cata-Clean the month before. It did clean the cat very well and improved the gas mileage but with these additives you have to try them very far apart. Especially with some of the solvents in some that can react with alkalines in others. My case was unique because the SUV I bought had sat for a year while waiting for an engine from Ford. So the cat had to be changed out as well as the sensors.
The tactic in this video seems solid and if I had not tried the other cleaner I would have done this. Seafoam products have been a go-to over the years.
I’m going to try this on my 2016 sonata hybrid - the bendy straw seems to be an important part of this process
I changed all my 02 sensors 0n my 05 wrangler and code never went away think i may try this

Hi, thanks for informative Video. Can we apply it on gasoline cars or only on diesel cars?
Yes we can

@@NewBayERA it will not hurt the sensors. In my video I only removed the top sensor (upstream sensor) just to have direct access to spray the CAT. I did not remove the bottom one (downstream sensor) It did not harm the sensor.
Did after doing this did it help with fuel mileage? I’m getting the PO 420 code thinking about doing this cause I’m having very bad gas mileage.
Seafoam actually works in the oil, gas, ( & obviously in the exhaust too) says so right on the can.... Seafoam is great stuff. I had old gas in my Harley. I drained as much out of the tank as I could, by siphoning, since I didn't want to remove the tank. I was told by Seafoam to add a can of Seafoam to the tank with a gallon of fresh gas.... It worked great, cleaned up the fuel pump, injectors, hoses & lines, & any residual old gas & varnish!
@@donwendling7800 thanks for sharing. I didn’t know it could be used to clear out old gas. Will keep in mind for future needs.
Damn.. that’s badass
It would not work resovled. I put seafoam light went off few weeks later come on again. Sound like not help enough.
Sounds like the CAT is shot, but before you go replacing that very expensive part, I would recommend replacing the upstream oxygen sensor.
I’m a firm believer in the seafoam I use it in every thing to fuel oil the booster line. I also have had that rotten egg smell in my cat but did a few treatment of it and has gone a way. I will find out today or tomorrow if it really works after having my emissions done.
@@crushrreviews That what I wonder and thank for recommend. I am going replace when I can
Great it is the first video that really solves the issue. I just have a question: In the monitors (OBD II) does it show as complete? The issue I have is that It does not present a code but in the monitors shows the catalyst as Incomplete. and therefore it does not pass smog. So in you experiment, was the catalyst shown as complete?
You need to literally drive your car a couple hundred miles for the computer to reset it as complete. It will not do it overnight. Good luck

I use the Walmart super-tech brand with the Acetone it does a much job than sea-foam and it’s much cheaper Roughly three bucks a can compared to almost $9 bucks for sea-foam it’s more of a lubricant the Acetone is the primary ingredient in the supertech throttle body cleaner and I have is much effective in desolving carbon buildup and varnish good luck 👍🏽🍀

The carburator cleaner or parts cleaner? Man this would be my last option, i ve tried everything even removed it and soaked it over night! Def dont want to pay the $2300 for a new cat😩
I have two Cats (V6) and 4 sensors! OBDII indicates P0430 (Bank 2).. should I work on Bank 2 and ignore Bank 1?
By the way, if this works, it will save me $1,800.
Thanks.
If the code is indicating bank 2, then I’d concentrate on that one
Also, just curious if your spraying right into the cat and not the motor I would think it doesn't have to be seafoam..it could be brake clean, carb cleaner, etc
Brake clean or carb clean is completely different and fairly quickly evaporates so it would do no good. Seafoam sits there and penetrates the buildup in the cat.
When you are spraying the seafoam into the air sensor slot, does that clean all the banks of the catalytic converter. My air sensor is under my truck. Thanks.
@@brownyes6211 It will clean whatever cat sits below that 02 sensor. If you have 2 banks you will need to remove and clean each cat through the top of both upstream sensors.
@@brownyes6211 remember that it has to go through the hole of the upstream sensor not the downstream sensor. The upstream sensor usually sits below the exhaust manifold just before the CAT
@@crushrreviews Thanks for the information.
@@crushrreviews Thank You.
Can I use it on my 2018 Chevy Spark
Yes you can
Try & see if the purge valve is the problem 1st guys just my two cents
Does the secondary o2 sensor need to come off also?
@@hkarsp00lup31 no it does not, the downstream sensor does not have to come off.
Another proven and great way to do this is, let the tank get a hair below 1/4 , pour in 1 gallon of laquer thinner and run on the highway at speed 30 to 60 mins, re fuel. The engine 420 code will go away and the sensor and cat will be removed of slight impurities
Rest assured that Cata-Clean DOESN'T DO S**T.
DITTO.. been there; don’t that, I agree 100%.
Be careful where you put dielectric grease or any kind...because the O2SEN needs ambient air to function. Air is drawn in through the wire harness for comparison to oxygen in the exhaust.......I'm not sure if it applies to A/F SENSORS....BUT IT DOES WITH. ZIRCONIA SENSORS
yes soo true, it go into the exhaust. I was going to do the same thing before I just bought fuel injector cleaner and did a fill up. Drove it home says 10 miles, and the next morning started the car and the check engine light with that code was remove. But if that hadnt worked, yes i woukd bring out the 02 sensors and clean and clean where all opening and surrounding area too. We think so much carbon burn up cause all alot of error codes

does this only work for the bank 2 catalytic converter or does it go through bank 1 catalytic too
@@robertroman55 if you have a bank 2, that’s a separate upstream oxygen sensor. Bank 1 is passenger side of vehicle or right side of engine. Bank 2 is left side of engine or driver side. For each bank, there are two separate oxygen sensors, bank 1 upstream and bank 1 downstream, then bank 2 upstream and bank 2 downstream. So if your code is reading bank 2, then it would be the upstream oxygen sensor on the left side or driver side of the engine that you would have to remove and spray. But it would not hurt to do both bank one and bank two. I hope this makes sense and I’m not confusing you more.

Great video, thanks.
I just bought a 2010 nissan rouge and the service engine light is on and this is one of codes that came up. I ended up buying the Rislone cat complete system cleaner but haven’t used it yet. Unsure if I should try the Seafoam spray instead?
Car drives fine but shakes a little bit only when its in brake on drive for a while. Any tips or recommendations of what I should do? 🙏
Honestly it can’t hurt to do both. The Seafoam and the Rislone. By placing the Rislone in the gas tank you’re helping to clean the entire system. And by spraying the Seafoam directly into the Cat, you’re helping to clear up some of that carbon buildup. Again keep in mind that this is not a guaranteed fix for your code. It all depends on how bad the cat actually is. It may or may not work. For the price, it’s definitely worth a shot. Worst case scenario, you’ll help improve gas mileage and acceleration. If you can even call that a worst case scenario. Ha ha. Let us know how it turns out.
@@kaylasalas2you’ll need to rephrase that question. Are you having a shake on the steering wheel when you brake? Is that your question?

One of my previous high mileage cars has this code occasionally. I reset the code then notice that the code doesn't return until after refueling at Costco Wholesale gas station.
That’s odd. I can’t see how gas from Costco would cause it to come on. That could simply just be pure coincidence. Definitely puzzling.

Your monitors only run with a specific amount of fuel in the tank. Costco fuel has nothing to do with it.

@@crushrreviewsdo you think cleaning the 02 sensors would also be ok to do or just stick with original plan?
Seafoam is made to go into the engine in measured quantities. Read the package. Engine and gas.
@@src4409 it will cause no harm to your exhaust trust me. No need to measure quality when spraying directly into the exhaust

Think the foam work in dodge caravan?Just spray in cataylitic converter an drive it?
Spray into the opening after removing the upstream sensor, let it soak for about 20 minutes, then idle the car for about 10 minutes or so until the smoke dissipates. When smoking out the exhaust, idle the car at about 1500 RPM. It will help heat up the exhaust and burn out the residual Seafoam.
No need to drive the car, just follow the steps above.

did the P0420 code leave ? why didn't you show that .

@@KESSTHEMC you’re right ! I should have done the re-scan afterwards. My code was gone because it was a pending code, it had not become a permanent DTC yet. Unfortunately Permanent DTCs cannot be cleared with an ordinary OBD scanner. If your code is permanent, the problem would have to be corrected and the car has to go through about 10 normal drive cycles before the ECM clears the permanent code automatically.
do you have to reset the thing with that device before you test drive it ) or will engine light eventually go off by itself after you drive +/- 100 miles ?
You can reset it if you want to, but the computer will erase the code and turn off the light on its own after a few drive cycles where the problem is not present

Crushr how often do they have you check smog in your state? Do you have to have all your readiness monitors completed to pass smog? I am glad you got around putting on a new cat. I just replaced mine. You saved a lot of money.
@@dogsplantscarsneatstuff176 hi, and thanx for taking the time to watch my video. I really appreciate that. To answer your question, In my state “NY” we’re required to pass a smog test every 12 months. We’re allowed the following, up to two monitors to be in a "not ready" state for 1996 through 2000 vehicles and one monitor "not ready" for 2001 or newer model year vehicles. I’ve been good so far. Check engine light still off with approximately 201,550 miles on the odometer as of today. Now a question for you, was your CAT replacement expensive? Did you do it yourself? Just want to know for myself if and when the time comes for me to replace mine. Looks like a pretty easy DIY project.
@@crushrreviews At 240K miles my cat finally gave up. I may try soaking my old cat in a solution like lacquer thinner. Before I talk about the putting on of a converter let me say how disappointed I am in the warranty of the new cats: 25K! The bogus 50K warranty is only for the outside of the cat. In a state like NY where you lay down a lot of salt I be enforcing the warranty may be next to impossible. I did the cat myself but was surprised at some of the things I had to go to. All catalytic converters are expensive as you well know so I got mine off of Rockauto. I buy a lot of stuff off of them and have had few troubles although they are not known for being great if things go south with a bad part. Here is the big education factor: If you get just a cat converter those old pipe expanders that you can borrow from Autozone or OreillyAuto such as www.oreillyauto.com/detail/c/evertough/rental-tools-evertough-1-1-2-to-2-7-16-inch-tailpipe-expander/ren1/67096/v/a/2625/automotive-car-2002-buick-lesabre?q=exhaust+pipe+expander&pos=7 are not usually success in expanding exhaust pipe to slide your cat into. This one works on std. 16 gauge exhaust pipe with my Ryobi std. impact gun: www.amazon.com/Astro-Pneumatic-Tool-78835-Stretcher/dp/B01JBICBJ4?th=1. It is $100 to $130 on amazon. Harbor freight has one for $150. The original Lisle tool sells for about $215. If you do a second one this tool will pay for itself in money and frustration. I used band clamps to connect it the new pipe. Although I originally bought std exhaust clamps they crumple the connections and make it more work to remove components in the future. I went whole hog and bought the catalytic converter, resonator line, and the muffler all new. In Calif. I had the choice of buying a new Magnaflow cat from Autozone or OreillyAuto for $1300 off the shelf. I chose the Rockauto's AP/Eastern for $540. I got mine without the resonator since it was cheaper to get the separate resonator with the extended exhaust and the muffler from OreillyAuto with their 20% off sale. The resonator assembly and muffler were another $290. I got the 2" and 2.5" in band clamps from amazon at half the price of the auto parts houses: $8 vs. $15. I have 4 six inch high railroad ties that I drove the car up on securely. I couldn't use my creeper since I am a overweight. Not a great idea. I also used permatex ultra red to connect the exhaust bands to the pipe. Jack stands would have been better. Although the resonator and the muffler were from Walker they look so much wimpier than the OEM original. Here is the only nice thing I can say. The last two smogs (two years apart as per Calif. smog check) I had to drive 250 miles to get my catalyst monitor to complete. With the new Eastern cat I drove less than 40 miles to get all of them except my evap monitor which we don't have to complete in Calif. Although I could have welded the joints I wanted to make sure everything worked before I finalized the deal. Hope this helps. i am thinking about getting a home lift for my cars since the 6 inches was close for my car. People report sales of Quickjacks on slickdeals if you are interested. Hope this helps.
PS with band clamps you want to check them for tightness after a short time due to the expansion and contraction of metals and the possible leakage of exhaust pipes. Hope I didn't miss anything. Feel free to ask more questions.
thx for the feedback. Very much appreciated, I will definitely keep that in mind. Somehow sounds like a lot of work.

How do I do this on a 2003 gmc sierra 1500??
That one is a little tougher to do because of how the pipe bends after the O2 sensor. But with a long enough spray stray you might be able to get at it. Just be sure that you swirl the straw around as best you can to get at most of the cat. I believe you’d have to go from under the car for that one.

I would say no as the cylinder combustion would burn Off the sea foam into a gas before it reach the cat.

Going to trying it on 2008 Lexus IS 250. On the weekend and update
I have the PO 420 code for both the cats .. Would i have to do it for both? bank 1 and bank 2 codes

@@crushrreviews thank you!
can we try with dishsoap and water and let it run ?
WTF! Dont be cheap! The answer is NO!
@@LOLONO666 Hi there, I don’t think it would be as effective. I know people have removed the catalytic converter and soaked it in soapy water several hours, but as far as treating it with soap & water while still installed, I don’t think it would be effective. Save yourself the trouble and use the Seafoam, you’ll have much better results.
1:44 mark is where the ding 🛎️ stops lol 😂 goodness gracious
@@kdtxtooldad 😂 I’m sorry about that. All I had to do was close the door but it was HOT out. I didn’t think it would be that annoying on the video. Removing the key was not an option because I was showing the code reader. Thanks for sitting through it. ✌🏼
Good stuff 👍🏼
Did it get into smog ready?
My car is not yet due for State inspection, but I can tell you honestly that if it was to go through state emissions inspection it would pass guaranteed. I’ve scanned the system it has no pending or permanent codes, and all emissions sensors are compete and ready. I show that on a separate video. Here’s the link below to that video
