- 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.
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.
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
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'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 ?
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
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 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
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.
Unfortly most of us have old dirty cats. And the dreaded code. Cataclean gets good reviews
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.
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
30 minutes I’ll never get back..
How about you post a synopsis of the video to save the rest of us from wasting 30 min too
What are you trying to prove? You changed the main part these products are suppose to clean then say they don't work.
I used the CRC it cleared the check engine light, and the car runs better.
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 ?
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.
INVALID TEST! You completely wasted your time on this one.
1) You never installed a new downstream O2 sensor. (The front sensor doesn't show or have an impact on cat efficiency).
2) You installed an aftermarket high-flow cat. High-flow cats have less catalyst allowing for higher exhaust flow but do much less "cleaning" of the exhaust which makes them much less efficient...
Those 2 things alone will never get you where you want to be as far as this test goes. You would have been better to have left the old cat and change out the rear 02 before trying these products. 🤪
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.
Same man. It's the only that worked for me. I could be wrong, but I think Scotty said, at that time, gumout is the only product that has the PEA in it.
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?
spark plug spacer
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).
Thank you for your time sir. U saved plenty of consumers of wasting money.
Clean those clogged drains for the sunroof to fix the water backing up into the pillars of the car
I think you did a great job testing all the chemicals so far. You are great, man, thank you.
I have used the B12 manny times and it really works good, it cleans your plugs and really does everything it says on the can...your motor will run smoother using B12 and you will get better gas mileage...🇺🇸😎☕
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?
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.
Long and short term full trim should be watched with o2s, vacuum leaks(bad PCV) can trip it, dirty MAF, cracked air intake etc....
P0420&P0430 can not be fixed with 02 sensors.
Go on I'm listening!
The Berryman B12 chemtools primary active ingredient is Acetone
Is that good or bad?
Acetone can swell rubber o-rings and hoses. I suppose it depends how long it stays in the fuel system exposed to rubbers and the amount of acetone.
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 😊👌👍
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.
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.
Hello I just saw your video on the Pontiac vibe po420. Did you ever resolve the issue?
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.
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!
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.
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.
I'd like to see the Scotty Kilmer gallon of laquer thinner.
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.
Rockauto, Denso O2 sensor for 2003 Pontiac Vibe is $42.79. Denso is Toyota OE.
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 think you spent more money on chemicals than what the o2 sensor would have cost you
I absolutely did. The sensor is like $45, the chemicals I spent about $60 on 😀
I was thinking either sensor, sensor wire or exhaust leak. It doesn't take much.
My experience is to install only OEM catalytic converters or risk tripping codes by using cheap aftermarket cats.
Absolutely!...
'IF', after TRYING some possible fixes LESS than
$300+.😳

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
Thumbs up for your hard work.
It's an interesting video.
If the Cat is new then why try all these different products instead of replacing rear O2 sensor?
Because the products all purport to cure the 02 sensor code, and the sensor is working, doesn't have any faults.
My 2005 Toyota Sienna has 310,459 mile on it and now it show a catalytic problem but no check engine light and it NEDS the California style. The car is not worth $2000 for each one I need 2, for that price. I don't care if I have to take it off to clean it I just want to know if that really works. 😢
BG 44K
No matter what code any check engine light is an automatic emissions failure, even if the light is off there's pending codes until drive cycles are complete and reediness monitors are set.
The 420 code is directly related to the 420 code, the VVT codes are causing the CAT code because you're either running it too rich or too lean and that will damage the catalyst. Timing Chain or Belt likely needs replaced (depending on which you have) and yes timing chains do stretch and throw the timing out of sync.
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?
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.
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 ;)
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
Scotty Kilmer says a gal of lacquer thinner to a half tank of gas. Gonna try it. My O2 upstream bank 1 went out. Replaced all O2s. Then PO420 came on. 20 bucks...vs New CAT. Gonna try thinner
Have you tried it? What was the result?
Emissions is a joke and should be gotten rid of. Its only there for people to make money. Good running vehicle but not legal to drive. Kiss my butt
All those chunks and pieces of carbon are getting stuck in the Catalytic Converter that will cause problems down the road.
I had the same problem on my 2004 Honda accord sedan ex 4 door I relaced the whole exhaust and sensors and cat and guess what it came back on went away and came back , I guess unless we spend 600$ on a cat it won’t go away and I’m not doing that for some drg head to steal ya know 😂😂😂
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!! ?
A cleaner must contain PEA as a cleaning agent to really really work. Gumout is the only one i know right off that conatins it. Who knows if it would work for this situation tho.
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?
I drove 700 miles on Rislone and back on again!
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
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.
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!

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.
But if you got a clean cat, why are you running products to clean the cat? I mean, if you know the cat being dirty is not the problem, why trying to fix the code with a product that promises to clean the cat?
Fair question, because these products are often touted to "clean or cure" the O2 sensor and the code as well.
@@LucoreAuto I thought that they were meant to clear the code by trying to “clean” the catalytic converter, whenever that would be the problem. At the end what was the real problem? Was it the O2 Sensor?
Amsoil P.I. or RXP Gas Kicker = best quality
Thank you for your good work that would save us alot of time and money

I’m commenting before I watched the whole video because I don’t want to forget… Yes seafoam, Berryman, gumout, and the Walmart brand super tech share the same bottle but accept no substitute… Seafoam is the real deal… The others, I’m sure they’ll clean injectors through the fuel system which would be fine but as far as soaking things in the off brand stuff or using it in your oil or doing the hot soak I would highly recommend not using it in that way. Seafoam is really gentle on rubber seals and sensors but the others are not… I’ve been using seafoam for years. I replaced the head gaskets on my 96 ford ranger a couple years ago. It ran hot because of that stupid vacuum actuated valve that allows coolant to flow to the heater core and a feller didn’t catch it in time… Anyway, when I had the engine apart it looked spotless on the inside, not gummed up at all and believe it or not you could still see the factory crosshatch in the cylinders from honing… Anybody that doesn’t believe me can do their own tests at home… Soak a rubber seal or O-ring in seafoam and the others in the off brand stuff for a few days and holler back at me… Just trying to help save somebody a lot of heartache later on down the road… My 96 Ranger has over 300k miles on it by now I’m sure… It had 170k 13 years ago when I got it, I was rolling to a stop and pressed the button to reset the trip meter and stripped the gears to the odometer and never replaced them… But rest assured that truck has seen its fair share of wear and tear… I used it as a work truck hauling mowing equipment and I even towed a few cars with it from a few counties away…😅 Including a mustang with a 302 and 351 Cleveland heads…😂 Yes it’s possible to put big block heads on a 302w… Just not very logical nowadays… Lmao 🫡✌🏼
Ok I watched the whole video… I just like to stay up to date on the latest, greatest, snake oils…😂 Just so you know I’m not bad mouthing Berrymans or any other brand. I’m just saying seafoam is my snake oil of choice…😂 I will say this, I had a friend that was commercial parts pro at advance auto parts and he said mechanic shops would order cases of seafoam to help cars pass emissions when Tennessee had their little spat with emissions… They went back to no regulation now… But from what I heard, they would do the hot soak… Rev the car to around 2500 rpm’s and take the brake booster line off and slowly pour the seafoam in the vacuum line blocking part of the spout to control the flow of seafoam and towards the end of the bottle they would pour a little heavier until the car dies and let it soak for a while and supposedly they would pass with a dirty catalytic converter or whatever… Idk, I’m just repeating what I heard… Take that with a grain of salt… But I’m sure they weren’t buying cases of seafoam for the hell of it… Cool video, I’m gonna check out some of your other content and possibly subscribe… Even if you feel like this was a failure, it wasn’t maybe you’ll save some poor guy a lot of money throwing snake oils at a problem that can’t be fixed without replacing the defective parts… Did you pull up live data and see if the oxygen sensor had any signs of life or if it was just flat lining? Thanks for the video!
@@jimmywilson1388prefer Seafoam instead.
When resetting the ECU "manually" i.e unplugging the battery, both of the O2 sensors need to be taken out from their holes and cleaned. When the power is switched back on, the cleaned O2 sensors need fresh air for the base line reading. Let the ECU run it's initial cycle, but DO NOT START THE CAR. Then turn the key off, screw the O2 sensors back on without unplugging them (that's the tricky bit) and start the car. I've done this succesfully several times without ever having a scanner/computer to clear the codes. On the Vibe's case, I'd argue that the after market cat is not efficient enough, or there's a small pin hole before the O2 sensors that mixes the exhaust gas with oxygen richening up the initial A/F mix.
& hoOoowe, dU U perpordt, would extra air contribute to richness(mOr fuel) in an air fuel mixture?🤔
@@ezwa9979 Old exhaust manifolds/pipes become pitted with corrosion pin holes. When the exhaust pulse travels past these tiny holes, the pulse sucks air through the holes. When these pin holes occur before the O2 sensor, the extra air gives false reading on the O2 content in the exhaust gas, so the ECU adds more fuel thinking the AFR is lean.
Same thing happens when the O2 sensor is not calibrated correctly. If the sensor at it's calibration phase is sitting inside a fuel soaked exhaust pipe, it thinks the fuel saturation is normal. So it feeds extra fuel into the system trying to keep the pipe saturated.
The sensor(s) send a voltage value, which then is read by the ECU and interpreted by the values installed in the memory. These memory banks can self clear if the battery voltage drops too low, or battery is disconnected long enough to drain the capacitors on the ECU motherboard. At this stage the ECU automatically goes through the start-up sequence including sensor calibration when plugged back on.
Ugg, so extra air can cause a running lean OR rich conputer snafoo?😯, guud grEEf, computers👋 it seems there are like 20-30 things that can cause this running rich cunundrum, coomm.. pUwtrs.
@@ezwa9979 Extra air in intake, lean, extra air on exhaust, rich. wrong calibration/broken sensors, rich to prevent engine damage. Up until late 00's the system was relatively simple, after the emission regulations larger engines became unmanageable. The basics are still the same. Things rot, get clogged and start to leak just like they always have been doing. Due to the efficiency demands, a lot more heat is created with tighter tolerances, shortening the average lifespan of the parts, although the parts themselves have been improving exponentially over time.

thNx, & what would you call the pcv loop? intake or exaust - or that spare air valve that looks like a pcv, but isn’t(same L shaped plastic, but not even a fake pcv valve), just lets excess air from valve cover 2, back to throttle body). what would you call those hoses, intake or exaust?
I nag you with these questions because, my cat. & or oxygen sensor codes started popping up RIGHT AFTER I fixed a few leans.. several times I’ve reset ECU(although there still could be carbons, etc., stuck on all the oxy sensors, cat., etc., from when it was intermittently(it was) running lean) & computer adapted, & then rich. now it either my new cat., clogged up cat & or older oxy sensor, or vvt, pcv, egr, this that or 25 other things👋, guuud grEEf😑.
Good God man get yourself a proper funnel 🤦♂️
I would and I'm sure everyone else would like to know what the fix was?
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
My concern was will the cleaning deposits clog the converter?
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!
The voltage from an o2 sensor is one measure of it working….heater circuit and cross counts is another. Look into it
I had to replace my catalytic converter twice in one year..My engine burns about 3 quarts of oil per oil change so pretty sure that's why mine go bad.
Just straight pipe it
With all the money you spent on chems and gas you could have just put in a o2 sensor for 20 bucks
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.
Pull O2 sensors out spray them down with carb cleaner get as clean as possible then run a carbon burn off (sea foam carbon killer) that should clear the code and make it run awesome cos gti vvti vtec and eco tec are bad for carbon build up because of the emissions sensor recirc in the intake or the EGR
I had a k24a8 that kept doing the same thing I run injector cleaner cleaned the O2 with carb cleaning and washed in diesel then cleaned it off again reinstalled then done the sea foam carbon killer and EGR delete (as in australia that is legal) and the car has never run better and hasn’t thrown a code for left bank (O2 code normally) or cat code
Your new catalytic converter may not be up to your manufacture standards so the light may be permanent
That IS also a possibility these particular cars are pretty sensitive
I tryed all these camicals and it did not witk for me ether
Try Cataclean, I've seen good results.
I had a mechanic, who has since passed away from old age, and he hated cats, so he would just pour about a half gallon of laquer thinner in a full tank of gas and tell you to run it up and down the highway, and it seemed to work.
So after watching tons of cat cleaning vids from in tank potions to full removal and soaking in soap and water to sodium hydroxide to lacquer cleaner/cellulose to caustic soda to jet wash to compressed air blast. Nothing actually works. Sure a load of crud and muck comes out on many vids but the cars never run better. Seems that even when the honey comb structure is intact (wouldn't be worth cleaning if fallen apart/disintegrated) the cats lose their ability to do the job due to age and perhaps once contamination has occured the damage is done. Only one thing for it. Save your money on this task and just buy a new cat.
Yeah, that’s my final verdict after videos, mechanics, and owners clubs. If you don’t want to see the code, install an illegal spacer on your O2 sensor. If you want to pass inspection, a bottle of miracle oil might do the trick. If you want the code to go away, have your vehicle running most efficiently, and save the planet, install an OEM cat. Period.
sometimes it takes couple of weeks for things to work
did you replace the fuel filter? theyre nasty dirty most of the time
Tried crc for a cat code. Didnt work so I used an o2 sensor spacer. Havent seen the code in 2 years
That's TECHNICALLY not fixing the issue, just taking the sensor out of the exhaust stream so it doesn't trip a code 😉
@@LucoreAuto oh absolutely. My state tests for emissions so as long as the check engine light is off, im good. Still has 2 cats, hopefully they work
@@malrofo as long as no one rolls up under the car to look, no one's the wiser 😉
@@LucoreAuto Fortunately that state isn't commiefornia
If you dont have a gas cap it will turn on check engine light ...
Have a gas cap, show taking the gas cap off multiple times in the video 😉
TRUE
It looks like someone's getting double his money back.
So....did you ever fix it? If so, what was the actual cause?
Still actually on ongoing issue, unfortunately not long after this I grenade the transmission. Code is still there, just brought the car back to life recently will have to do a followup video to this actually.
i use chem-tool and i get better gas mileage,and it will also strip paint
Do you even have a gas cap ...
Did you even watch the video? I literally unscrew it multiple times on camera 😉 the fuel door is just broken off
@@LucoreAuto you dont see that until the end austin ...
@@707SLAYER 4:05 is the first time 😉
I Put WD-40 in my Engine Oil and in my Gas Tank every Fill up.
My SUV's Have never Ran Better. PERFORMANCE IS DAY AND NIGHT DIFFERENCE.
It worked Better than Marvel's Mystery Oil Hands Down.
