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.

​@@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.

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 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! ***

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'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.

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 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.

Plugged muffler or collapsed expansion joint from previous cat?

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.

@@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.

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

That vvt code can trigger o2 codes as well

I was told to take the upstream O2 sensor out, then pour the seafaom in so it can sit in the cat, wait an hour replace O2 sensor and start the vehicle.

@@brettluster7967 Not yet. I'm a bit apprehensive about trying it.

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 ?

30 minutes I’ll never get back..

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!

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.

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

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.

Put the seafoam directly in the catalyst converter run for a while then road and it worked for me

Hmmmmm yikes not sure wanna try that with a brand new cat!

Did you get a big puff of smoke with the sea foam ?

I would and I'm sure everyone else would like to know what the fix was?

Did u have to replace both o2 downstream sensors

Unfortly most of us have old dirty cats. And the dreaded code. Cataclean gets good reviews

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...

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

Ahh, is that temp license plate going to be your plate? VIBE3R8R? That wouldn't get by the censors in Michigan. Good luck with that plate. 8-) My custom plate is VIBENUT.

Can we get a update? Love the vids and I'm new here

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+.😳 "Spend Not ALOT , until you give less $ a SHOT." 😀😎👍🏼

put a spacer on the sensor after the cat. High flow cats dont let that last sensor read properly because the stream hitting the sensor is a faster stream with a high flow cat so moving the sensor back with a spacer will take the sensor out of that stream and allow it to read properly and turn your check engine light off

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

Great demonstration and video however, the only flaw is you should have run at least another half a tank of gas through it clean without any additives before you added the next one, otherwise you potentially are just mixing them which could either cancel or provide better resultswithout accuracy. Another thing that I noticed is, I do know for a fact, a couple of the products you used are technically not equipped to deal with the added ethanol that is put in the gasoline today. Therefore, the ethanol potentially reduces results or eliminates results because the product is not formulated to deal with gasoline and corn alcohol.
