Sorry, just another snake oil video. All these sprays and liquids do, at best, is mask symptoms. The underlying issue is still there. Putting off real repairs will only make things worse. The reason our vehicles throw DTC's (error codes like P0430) is to facilitate diagnostics. So, use the data and do a real diagnostic! Look at DTC (error code) freeze frame data, analyze live data streams of voltage, amperage, and switching for pre and post CAT O2 sensors, short and long term fuel trims, fuel injectors, misfire, MAF, etc., etc. Do a smoke test for small exhaust leaks. Check inlet/outlet CAT temps. Diagnose! And if none of this makes sense, take it to a qualified mechanic. What's really funny is how people complain that their O2 sensors go bad and expect snake oil to fix them when it's (supposed to be) common knowledge that O2 sensors are maintenance items that should be replaced routinely, usually more often than spark plus. Yet, very few people do that and dump Dr. Gooberhead Mystery Oil into their motors. Crazy.
I used a bottle of Cataclean put in through gas tank and my error code didn't come back for a full year. Roughly 6000 miles. So, I guess I'll do it again maybe with a bit higher concentration this time.

100% did not work on my clogged catalytic converter at all.
How much of it did u spray in there?
hell yeah this worked for me. still should get the cat replaced which i'm going to do right away. but at least i don't have to get it towed. thanks!
Would oil additive such as at-205 cause this code to come up?
P0420— replace your catalytic converter!!!!!!!!!!!!!
Bad temonstator! You keep shaking the bottle.
wasted my $20 and 3 hours to run 150 miles still not working

Use a milkshake and your problem solve.
It go's in the gas tank
did it work? long term i mean.
i got p0420 bank 1 in a 2010 accord replaced both up & downstream 02 sensors but that wasn’t the issue because i was losing MPG so save your money lol
This shit aint worth it buy dpf foam spray and spray it thru the oxygen sensor
Do this before you sell a car

Hold the damn can steady
Stop wasting $
Cataclean is safer
Dirty O2/Catalyst/DPF signifies DIRTY ENGINE and very likely CLOGGED EGR-Valve
