Product Testing! Seafoam VS Rislone VS CRC VS Berryman do they work? Can they fix a P0420?

- Product review videos aren't what we normally do but in this case we've got a P0420 Catalyst Efficiency code repeatedly popping up on the Pontiac Vibe GT and figured this would be a good chance to test some "over the counter" products! So let's do some scientific testing shall we?
Product number 1, the classic Seafoam. Product number 2, Rislone Fuel, Exhaust & Emission system cleaner, Product number 3, CRC Guaranteed to pass Emissions System Cleaner, Product 4 Berryman B12. These 4 are all products sold over the counter at just about any auto parts store and are purported to "fix" or at least temporarily improve the issue we are currently having.
Just before the making of this video we HAVE installed a brand new FlowMaster 2.5inch high flow catalytic converter, running the factory original rear o2 sensor in the factory location on factory pipe. - Авто та транспорт
What product do YOU believe in most? What would you do/test next?
I believe in new spark plugs, have y’all changed the plugs and air filter?
I would change both O2 censer's, would deffently take them out of the equation if it still does it.
I would replace the rear O2 sensor. I've yet to break one removing it using a proper 6 point O2 sensor socket. I love my inductive heater which has yet to fail me getting a nut / bolt out. Spent $420 for mine but it was the best money I've spent on a tool and I swear less now. 8-) Easy Peasy.
I own a 02 Camry XLE V6 they are a Finicky little 👿 and engine light has been doing the same thing I have used catclean which is supppossed 🤣to be the best I might as well peed in the gas tank and I replaced O2 sensors with Denso Brand Still ON , I Took it to Mechanic he's baffled and he also checked the temperature of the Cat's it runs like a Scalded Dog next thing I might try is a Smoke Test because after reading About my Precious little Baby if Toyota especially detects a exhaust leak it sets off the Code, I have even tried the cheaters that you screw in where the 02 sensor goes didn't work, Ohh Yeah remember I said Finicky when the light is on No Stability Control or Traction Control. Good luck 🤞 on the Vibe can't wait to see the Outcome 👍
I have used cataclean to clear a p0420 and it lasted for 5,000 miles on a V8.
I had the same problem, I just replaced all my o2 sensors and the code popped back on so I removed them all and sprayed them with throttle body cleaner and also sprayed a whole can in the hole where the o2. Sensors goes and turned it on for a few seconds, installed them back and it ran really great and no more 0420 code.Try spraying throttle body cleaner inside the Cat and make sure to use the little red straw on the can so you can reach inside and spray a whole can,then do the same on the other side my friends.
How did you learn to do this ?
did you turn back on before 02 reinstalled ? or did I miss read thanks
Sounds like a recipe for a car bomb
@@juliawei8990lots of mechanics know how to do this. Carburetor cleaner and/or brake cleaner will also work. If you use brake cleaner just make sure it's the one without chlorine. We use carburetor cleaner followed by brake cleaner without chlorine when we did it. We left the engine running and sprayed it through the hole where the O2 sensor goes before the catalytic converter. If you have a O2 sensor that is not working, you can't simply clean it as the sensor is not doing anything. I always tell people I recommend cleaning the catalytic converter in this way before you replace the O2 sensors, that way you don't dirty up the brand new O2 sensor. After you spray a can of carburetor cleaner through the top hole (closest to engine, in front of the catalytic converter) while the engine is running, when you are done, then replace the O2 sensors. This will almost guaranteed fix your problem each time. This saves you about $800 by not having to replace your catalytic converter. If this doesn't work, you can then remove the front O2 sensor again (The one closest to the engine before the catalytic converter), poor about a quarter of a cup of Dawn ultra soap down your garden hose, stick the garden hose up your tailpipe as far as it will go, then take a washcloth or old shirt and jam it around the garden hose where it enters the tailpipe to form somewhat of a seal. Turn the garden hose on a little, and watch the hole where the O2 sensor was before the catalytic converter. When water starts coming out of this hole, immediately turn off the water hose. Let that water sit in the exhaust system for about 10 to 15 minutes. This will break down all the nasty stuff in your catalytic converter. Then remove the hose and rag/shirt. Allow the water to drain out for about 10 minutes before starting the vehicle. Do not put the O2 sensor back in that hole, until you start the vehicle first and run it for about another 10 minutes. This ensures that there's not too much back pressure on the exhaust system. Then replace the O2 sensor, and you should be good. You might have to possibly run another can of carburetor cleaner/brake cleaner (without chlorine) through the catalytic converter again.
I sprayed seafoam directly into the catalyst ran it for about one hour then highway it did the job for me
I think you did a great job testing all the chemicals so far. You are great, man, thank you.
Thank you for your time sir. U saved plenty of consumers of wasting money.
I have used Lucas oil fuel treatment mostly over the years just for maintenance. Absolutely no injector, fuel or catalytic converter issues on several cars I ran to almost 300,000 miles. Recently, I tried the Seafoam (it was cheaper) and it works pretty good. The one where I felt worked the best was Royal Purple Max Clean Fuel System Cleaner. I bought my Ex a car so she could take our son to school then therapy after and took her old beater to drive. That car had horrible mileage and a miss, it was clear she hadn't done maintenance on it for a while. I added that Seafoam, no change. Then I tried the Lucas Oil, no change. I tried the Royal Purple Max Clean Fuel System Cleaner and the miss cleared up quickly and the mileage improved. I now add a can of it to the tank about every two months and it works really well. *** My doors leak yours do so I can't wait for the video of how you fix it! ***
Thanks for thr information
Cool thanks
One thing for sure !! That car should be as cleaned out as much as I was before my last colonoscopy test !!! 😂
You would think so! 1500 miles of system cleaners should have gotten her a BIT more squeaky on the inside!
😂😂😂😂😂
rr=q😅
That's should really be clean lmao
Austin just proves those quick fixes are not what they say they are. Thanks for sharing! ❤️
Why anyone would think it would have worked with a brand new cat is beyond me.
Any time I’ve used a high flow cat I’ve had to add one of those spacers to post cat 02 sensor and that’s worked miracles
I did seafoam, duralube and rislone. Of course each tank replenished. Rislone worked but I think seafoam and duralube basically softened the build up enough for the rislone to work.
Long and short term full trim should be watched with o2s, vacuum leaks(bad PCV) can trip it, dirty MAF, cracked air intake etc....
Thumbs up for your hard work.
It's an interesting video.
Luckily, I was able to do this for my mom's 2011 Honda CRV. She had about 155,000 miles when the code came up.
I used 2 cans of Duralube cat stuff. It worked. About 3000 miles later, still no more warning.
I replaced the upstream and downstream O2 sensor a few thousand miles before that, because MPG was dropping.
Do you put two cans of the dura lube at the same time?
@@judyfroemming7756 No.
One can per tank of fuel.
Halfway through the second tank of fuel, the light went out.
When did you replace O2 sensor ? @@skylinefever
@@juliawei8990 About 15,000 miles before the light came on. I replaced both the upstream and downstream.
Rockauto, Denso O2 sensor for 2003 Pontiac Vibe is $42.79. Denso is Toyota OE.
I've had the best results with the CRC product. I run it down and then add super unleaded and monitor the test results on my code reader. In Texas I can have one incomplete code and still pass inspection, and the CRC buys me enough miles/time to keep the check engine light off. I have left the test center several times and the check engine light comes on right after I passed inspection.
Ha, ha, ha.......lucky you !!!!!!
Do you clear the code before input if the CRC ?
Thank you for your good work that would save us alot of time and money
2007 honda fit po420 cod
I have changed o2 sensors but cod came back. Nice video.
I feel your pain. I go through this crap every year with my 07 Suzuki. How did this turn out for you? It took 10 years before this BS started with me and the P0420.
At least great try and costly at your end to get us some experience, sir.
Thank you.
That was kind of my take on it as well, and really never expected this video to go much of anywhere. Worth trying $70 worth of products and run a few tanks of gas through to see if any of this stuff worked. Thanks for watching and helping to offset the cost of making the video!
Guaranteed to pass only works temporarily. That’s why they say to take the test when it gets down to eighth of tank. I believe the issue you’re having is an exhaust leak before the sensors or it’s the cat itself. I know it was replaced but if it’s a universal you might as well just replace it with a glasspack or cherry bomb. Factory cat is what you’ll need. Try using a spacer between cat and sensor. Check live data to see performance of sensors but it seems from video the sensors are working. Also remove egr valve and check small passages could be clogged.
I just cleared mine and passed smog in CA 2008 mazda 3 170k... i first ran seafoam high mileage in gas and oil combined with full bottle of seafoam injector cleaner.. i ran out half the tank then bought 2 bottles of cataclean, i hooked up one bottle of cataclean like an iv and fed it right into the throttle body.. i reved the car for about a minute bouncing off the rev limiter a few times.. after half a bottle of cataclean through induction the car was cranking out thick wite smoke and dripping black condensation from the muffler. I shut off the car poured 1/4th of the cataclean straight into the air/fuel bypass chamber, closed up the intake. I cleared all the codes missfire, and p0420 p0421... after driving normal for 200 miles it was ready to smog and it passed.. the car is running like new. Lets see how long it last.. while i was at it i replaced the air filter and cleaned mass air flow sensor and throttle body then did an oil change
Thank you for all your efforts
It would be interesting to see the top of the pistons with a bore scope to see if it cleaned the surface of the pistons with all those additives. Thanks for the testing.
I've actually considered the same thing. Planning to pull the plugs and do a compression test of it as well, could knock those out at the same time.
As some one mentioned before the problem is the Hi-flow cat you need to use a mini-cat O2 sensor defouler or extension some call it that will solve the problem
Have you tried unplug it let reset itself.,an the rear O2 sensor that could be faulty from straight out of the package. If it's already been replaced once before.
I was told to run 93 octane it through it, and it will clean it up. After that my 02 sensor went out. So I don't think running high octane is good in a vehicle that doesn't take high octane. Could be keeping it from clearing up the code.
Hello I just saw your video on the Pontiac vibe po420. Did you ever resolve the issue?
Is that toyotiac got gdi? There's a seafoam spraycan with about a 18inch spray tube, might do the trick. Good luck.
Thank you for being honest.
You just thanked a machine for the gas receipt. Awesome.
Always be polite even when no one's looking 😉
Check your work on the piping. Make sure your joints are air tight. If that is tight. Then Replace the O2 sensors. You know the cat is new and clean and you know the fuel system is super clean from the snake oil.
Great video Mr. Austin just wondering now that you have documented proof that the product do not deliver as promise ,are you Going to exercise the product guarantee of money back and/or double money back ??
That would be a very interesting process !
I was thinking either sensor, sensor wire or exhaust leak. It doesn't take much.
Well made video, thanks 🙏
sometimes it takes couple of weeks for things to work
did you replace the fuel filter? theyre nasty dirty most of the time
I have a friend that had cats stolen from his tundra and he bought some aftermarket ones and the same code started to happen no matter how many times the codes are cleared. He then installed original cats and the code went away.
All the sensors and ecu work together. High mile/low maintenance vehicle, I'd start with cleaning the MAF sensor. I'm guessing you want to leave active scanning out of the process i.e. monitoring short term fuel trim/long term fuel trim.
I have no problem doing active data monitoring to verify things are working as they should, in this case I used it to confirm the front sensor is see the typical rich/lean situation and the rear is seeing a much cleaner signal. Can certainly clean the MAF sensor that's a pretty easy to do bit, what's your thinking?
Plugged muffler or collapsed expansion joint from previous cat?
What would be the fix for P2097 code after replacing o2 sensors as indicated on diagnostic data? I’m having trouble clearing that code.
I did not have this problem until I replaced the transmission. I hope this product will work.
I had the same thing happen after a transmission replacement. I just saw water dripping order the vehicle. I called under there and found two exhaust leaks. One at the crossover clamp and one at the muffler clamp joints. And yes an exhaust leak downstream of the cats can cause the P0430 code. I'll soon be headed to a muffler shop to repair those leaks.😟
This can happen if the mechanic had to remove exhaust and did not assemble it back correctly or cut corners. Best bet is to take it to a muffler shop and have them check it out. Or if you have a smoke machine do a smoke test and it'll show all the leaks you have under there
I would check to see if there is an exhaust leak before you last downstream sensor
I used the CRC it cleared the check engine light, and the car runs better.
Nice video!
Why did you not clean the sensor directly soaking in the several products. Then hot water as a cleaner vibrating, then dry.
An agitation will show carbon removed.
Clean those clogged drains for the sunroof to fix the water backing up into the pillars of the car
Seafoam saved me from rebuilding my xl600r carb after the bike sat for 8 years in a private garage 250 miles away. After burning 3 tank full of gas it was unnecessary to rebuild it. Ended up rebuilding the bottom half (crank) , the top half I rebuilt just before it came to resting for 8 years.
Would the carb cleared after using gas only? Well, after 2 tank full and sputtering and stalls it didn't so I threw the hail mary ball of gas additive witchcraft for the hell of it and lo and behold. After 1 tank it was noticeably better by 50% and after the 3rd tank it was purring (well, as purring as a thumper purrs that is).
"threw the hail mary ball of gas additive witchcraft", What's that ?
That vvt code can trigger o2 codes as well
i bought a 2010 f150 that the oil pressure would drop and rattle from haitis, i got some rislone run it 20 miles and when i changed the oil the filter i drained out oil and it still weighed almost 4 pounds, all the crude was sent to it, i would strongly reccommend rislone.
I'm got an '04 Pontiac vibe I bought when it was almost new solid little cars I've got a 97 Ford f150 I couldn't get the immobilizer and alarm to shut off I unhook the battery for 2 months with the headlights turned on and I still couldn't get it to shut off So I grounded the positive and negative battery terminals together and let it sit for about an hour and It reset it I haven't had a problem with it since That was about 4 years ago
Dr Lucore Performing Experiments (lol) I use the sea foam just for maintenance. Cool video
Sometimes you've got to do a thing for science! We've used Seafoam many many times and have had some pretty good results on cleaning fuel systems/injectors up a bit. Unfortunately this maybe was a of a reach for just a fluid fix. Glad you liked the video Donnie thanks for coming along with us on another one!
I've always checked a catalytic converter with a laser temp gun. Drive down the highway pull off into the rest area the outlet of the cat should be 600 degrees plus warmer than the inlet. If it's working efficiently.
Hmmm not a bad idea, could be pretty easy to test that! Thanks for the heads up!
Same here.
Or you could just read it on the scan tool.
@@JohnSmith-xx1lx- There's temp sensors in the cat?.....🙄
@@PayNoTax-GetNoVoteNo. Typically people use thermal infrared temp sensors to test hot cat and exhaust temps.
I drove an 87 Ranger that when the rear o2 sensor went out, I was rollin' some coal! I never tried to fix the real problem, just changed the sensor.
Replace both O2 sensors, see what happens. Disconnect the battery, let the ECU relearn everything, see what happens. Still popping the code, it’s the cat not scrubbing enough to keep the computer happy. Problem solved?
Thanx for trying
Figured it was worth the test, if it fixes my car great, if not, at least we all learned something!
Downstream sensor only reads back post cat condition “cat not right” if it’s a 3rd party high performance cat you might need to spacer the downstream sensor but that’s illegal in most states ty for your honest vid 😊👌👍
...good testing data - still love the videos !...
I may have missed it but it says add a bottle of Rislone to 1/4 tank of truck, drive 20 to 30 miles and THEN add gas... So you added gas right after the bottle, was there a reason for that or does it not matter?
good thing he had small gas tank, cause if rislone one says 1/4 tank they’re being vague. he got it right to make it 1/2, which is a common ‘1/4’ish, but then he added gas, deluding the potency, 😩dMmmmnn himmn☹️. (ps., at least ‘cataclean’ says so many liters, something like 4-5 gallons).
If you haven't tried mixing them together in A tank of fuel. Then refuel up afterwards again only adding in some seafoam again into your fuel tank.
09 Nissan Cube with 120,000 and service eng light on for a year. Put Techron fuel system claner w/ full tank of gas. When at half full w/ check light on, put in Rislone cat treatment . Drove about 100 miles mostly highway up to 80 mph for about a third of that. Filled up at about the 60 mile mark, Light off.
Pontiac vibe GT was manufactured by Toyota. I'm having a problem with all of my cylinders misfiring, or at least that's what the torque app says. I think I have contaminated gas, because I annoyingly used a gas can that my little cousin tried to clean with baking soda and peroxide.
Is it possible to swap the O2 sensors to see if the code follows to the front?
Good question but no unfortunately they are completely separate types of sensors, and this motor being a 4 cylinder only has one front (upstream) and one back (downstream). Fair question though, certainly a great trick with spark plugs and coils!
Gumout turned of the 02 Sensor (check engine light) on my Jeep CJ .............. and it only took about 20 mins driving. Scotty Kilmer recommended a cleaner with PEA, so I tried it and it worked.
Did you get a big puff of smoke with the sea foam
?
I think you should try that reset you mentioned before spending any more money.
If you are using a flowmasters hi flow cat, you need to space the 02 sensor or that code will never go away
What do you mean you need to space the o2
@@forrestfuller6359 look online for 02 sensor extension/spacer they are easy to install and worked on my truck, they are cheap and worth a try
@@forrestfuller6359get a long o2 sensor bung/a o2 sensor spacer. It is basically just a pipe that screws into the o2 sensor spot and then you screw your o2 sensor into it.
I have had a lot of problems with aftermarket cats, I got 2 bad walker cats in a row, the 3rd one did the trick. But the aftermarket cats are junk.
Just watched this as my son's Volvo V70R had the dreaded P042 code pop yesterday. Now, this is my old R and it is NOT stock. Do I think the cat is bad?? No, I do not, this thing dyno's at 425hp so I'm not worried about that, do I think an O2 sensor is bad? most likely, but I was really hoping one of these products would actually do what they say they could do. But since I worked auto parts as a kid and through college I know that most of the time these products are just a gimmick however they do successfully do a tiny bit of good. You made a believable video that was fun to watch, thanks!
Thanks for watching, really appreciate that! And as a fellow turbo Volvo person, very glad to hear that! An angry turbo Volvo Wagon is our kind of thing for sure! You pretty much understand the point of this video, and why we figured we would make it. Do they clean things up? Ohh probably. Any time you are burning and running certain chemicals they DO do something. Are they going to fix a P0420 code? No probably not. Might cook off some soot, but that's about it.
I tryed all these camicals and it did not witk for me ether
You should have put a camera in each spark plug hole to show a before and after of how much it cleaned the carbon on the pistons.
top tire gasoline helps too I try and stay away from ethanol cheap gas with an PCV oil Seperator to stop the oil mist from going in to the intake .
YES! I get my gas @ Get Go in PA & JUST realized they're no longer top tier (stickers removed)! I googled for top tiers & says Sheetz was, & it wasn't. Says Sunoco is, so I have to check next trip out. A royal pain, but I totally agree witu YOU! ✊👍
Ive tried cataclean and rislone neither worked long term. My car jerks when acceleration at low speeds. Check engine light still on my hyundai accent
Car needs spiritual cleansing
The Berryman B12 chemtools primary active ingredient is Acetone
Is that good or bad?
Is it best to apply it before you fill the gas tank, or on top of the gas in the tank???
I recommend adding the cleaner around 1/4 tank and driving until you reach 1/8. Then add fuel to about 3/4 and run back down to 1/8. Rule of thumb is the more fuel you add the more diluted solution is. But each product is different and they tell you how much before and after on the box
Especially before an emissions test. Turns off code and all. You must have needed to change sensor or such. I have a 2009 Hyundai Genesis and a 2008 Mazda CX-9.
Since you tested the O2 sensors, I'd put my money on the high flow cats not doing what they're supposed to. To the best of my knowledge the O2 sensors after the cats are monitoring that the cats are doing exactly what they're supposed to be doing. I've seen plenty of 'High Flow' cats that don't actually do a dang thing to convert the exhaust to pass emission tests, so those rear o2 sensors will most definitely always trip a code.
If you don't care about the emissions since you know your cats are new and not clogged you could always take the rear O2 sensors out but leave them plugged in. Tie them off under the vehicle (somewhere safe) and plug the O2 sensor hole and call it a day. But remember that those sensors are there to let you know when the cats are performing poorly. They could always get clogged up and you would never know until your engine starts bogging.
Again, my bets on the high flow cats not doing a dang thing to convert that exhaust. May want to invest in higher quality high flow cats.
Got to try a 02.. I have had cat issue with aftermarket new cats. High flow cats have given us a few fits as well.
That's where we're most likely looking next is replacing the rear O2, not a HUGE cost as long as it comes out of the pipe ;)
@@LucoreAuto
Been there. As a auto tech it was fun to watch this. The yellow bottle has given us mixed results as well.
We don’t have emissions testing in Minnesota. I’m assuming you guys do there? Often times our customers are electing not to deal with emissions codes but we do do a lot of exhaust, especially lately lol along with people wanting to ensure maximum miles per gallon. I also really enjoy your expertise with the old stuff. Especially performance related alignments.
@@LucoreAuto 32 YEAR'S AND I HAVE NEVER SEEN THE LIKE AUSTIN..SHOULD HAVE JUST REPLACED THE O'2 WHEN YOU HAD THE CHANCE...WOULD HAVE BEEN CHEEPER I THINK..32 YEAR'S WORKING ON CAR'S AND I HAVE SEEN MORE PEOPLE BLOW MONEY ON SNAKE OIL TO FIX THEIR CAR...PO420 9 OUT OF TEN TIME'S IS AN O'2 ISSUE..REPLACING CAT IS USUALLY NOT A LONG TERM FIX ONLY BANDAID ON A BULLIT WOUND..AND YOU HAVE A SCANNER THAT WILL TELL YOU WHICH O'2 IS LAZY? RICH SHOULD KNOW BETTER...
It’s all a scam. Currently running high flows stainless works on my Hellcat with spacers. It initially worked for me, but now I have a permanent P0420 tripping. We’re talking nearly $3k per side to fix. I have the OEM so I will be using a rebuild service to have them refurbished for a fraction of the price prior to putting them back in the car, and may still run spacers afterwards as a precaution. They always figure out a scam to suck money out of consumers pockets.
"Scam" ? How ?@@meanmugmuzik7901
I've used the crc and have had good results
What did you use it on and did it turn OFF the light, or just keep it off for a bit?
Do you clear code first before pouring CRC?

OH-10!
What happens if you just ignore the p0420
My trans had po420, change out the O2, twice, but had to replace the cat, that cured it
What cat did you end up using? Something directly from Toyota? Walker? Something "Universal High Flow"?
@@LucoreAuto for my 2001 trans am , it was a direct replacement from gm, and the car only had 45 k
If you know the cat is good, why are you using cat cleaners. Vibe gt? 2.4L? It got to be burning oil they all do. Check for exhaust or
vacuum leaks yet?

What about Lucas fuel system cleaner? My dad swears by that stuff.
I have taken the downstream o2 out of the pipe completely, plugged the hole, and grounded the sensor so all it sees is fresh air. No cat code, even wit no cat at all.
Lol yes well that's not exactly FIXING the problem ;) That's just kind of a workaround to make the light go off ;)
The code just went off when I put a cat on my Prius. Was on when I left the shop. Off right before home.
My 07 toyota rav4 the only thing that worked was replacing the catalytic converter and no check engine light anymore
The voltage from an o2 sensor is one measure of it working….heater circuit and cross counts is another. Look into it
I would and I'm sure everyone else would like to know what the fix was?
See several high flow cats that just will not clean it up enough . The o2s just read to close to tell the computer that it's doing its job . Maybe a slim possibility that changing the rear o2 will fix it
That's high on our possible issues list that this high flow catalytic converter just isn't doing enough cleaning to make the sensor happy. It's certainly got a LOT smaller element than the factory unit and these Toytoa power plants ARE known for being quite finicky. Not totally opposed to a rear o2 sensor swap but nothing we can see in our data is pointing straight to a "bad sensor" it's reading and reacting as it should.
If the readings between the 2 are close it's a cat issue . Sucks the aftermarket can't get there game right . Look forward to seeing the fix
I drove 700 miles on Rislone and back on again!
Check for exhaust manifol leaks. Check for leaks around the flange. If there are leaks I thinl it will carbon up things because it may cause oil burning.
I thought bank one was the Upstream and not the downstream sensor
I .own and drive a Brish built 2003 GM asrta, 1.6 liter four cylinder , with 1.1 million miles on the clock and still runs like a sewing machine.. I Alway go with genuine parts , shouldent you!! ?

I've seen acetone/ lacquer thinner" being used in the gas tank as well". Hmmm " strong solvent" on old cars with carbs especially, rubber diaphragms o-rings fuel lines, ???? Newer flex fuel vehicles maybe a lil more tolerable but Damm "
Cataclean" ??? But would definitely use lucas ethanol stabilizer/ lubricant" after
The issue I have here is using so many different products 1 after the other? In my eyes that's really not an equal comparison. What if 1 products(s) helped clean it a lot before you use the next product so its not a fair comparison
Would like to see 4 different cars with the same problem use these 4 products individually. That would be a much equal comparison
code = p02F1 car = 2020 toyota Camry 4 cylinder, about 130K miles, Cylinder #4 injector circuit Range/Performance. had this one. first tried STP high mileage fuel injector cleaner. did NOT turn off the light or code. i used ancel ad310 and cleared the light but not the code. It would NOT clear the code. the Light came back few days later. But it did run little better. no longer had the smell of gas. A few weeks later. Tried Berryman B12 chemtool , (1/2 can and fill up gas , by the time it was to 1/4 tank the light had gone out. going to use the rest of the B12 Can on next tank) hopefully light stays out. Smog test soon.
When my jetta has that code it's alway the flex pipe section of cat pipe that is leaking
Can we get a update? Love the vids and I'm new here
My daughter's CR-V had the p0420 code and tried just about everything. I replaced the downstream O2 sensor and now no more p0420 code. Now I get a O2 sensor code. I got a Denso, so I didn't go cheap.
another guy was saying that when the ECU reads a new o2 sensor that the cat has to be clean and have clean fuel/air mixture
@blastztrixx9748 not gonna believe this but it was a blown fuse. It was causing the O2 code and a EVAP code as well. I replaced it and cleared the codes and all is fine. But the p0420 code is back again.
@@bearing_aficionado what fuse was it?
@blastztrixx9748 it's the FAL fuse. It's in the engine bay. A 15 Amp blue fuse. It will be located in a row of 3 15 Amp fuses. It will be the middle one. The FAL is part of the emissions and controls oxygen and exhaust readings. I was watching another video and it was talking about if you get a O2 and EVAP code at the same time that a relay was the culprit. I was browsing the comments and one poster brought up the FAL fuse. So I decided to check and sure enough that was my problem.
Don't know anything about cars. From my personal DiY experience could be electrical, could be also the fuel tank pump filter. Try also pouring some oil flush in the crankcase, like the same Seafoam, Luiqui Molly or same line of products...
