Hey there, I have a 98 Rav4 that was throwing P0420 a couple days before my fuel pump crapped out. Since your fuel pump is pretty similar, if not the same model as the stock one in mine, I figured I'd let you know. If your car just starts idling rough, losing power randomly or uphill, or just doesn't want to start, try swapping that fuel pump and cleaning/swapping filters.
My car since about 2015 has had a horrible idle, it seems to idle too low, and it shakes the whole car violently, it makes my nose itch and I sneeze from it.. But it only happens in drive at a stop light. If I'm in park or neutral, it's nice and smooth. It's weird. Thanks for letting me know! ;p
How do you know the cat was the problem, some cars a po420 can be caused by o2 sensors or even clogged fuel filters? Basically anything that causes a lean mixture at the 2nd o2 sensor.
I replaced my oxygen sensor so I know it's not that one. But this is supposed to also clean the oxygen sensor from what I heard. Although I replaced the wrong oxygen sensor it seems. I replace the upstream when not the downstream one. So that's a fail on my part.
Just add seafoam with premium gas and then from now on use a higher grade of gas and it will not come back on again....I did that with my car and code went away and stayed off a year ago
I don't know. I just heard it's something some people try so I gave it a try to see if it would get rid of the code. It didn't for me. I heard of this from another TH-cam channel called Scotty kilmer. It might work for some but it didn't work for me.

PS Rockauto sells them dirt cheap.

Hopefully no one was breathing in the exhaust. There's no way that's legal😂😂
Great tip though I love this
I don't see any reason why it's not allowed. It's the same thing as cataclean.
This is why TH-cam was made.
I enjoy making random videos. But I also make a not random videos at the same time. I'm almost making 14 videos a week between 3 channels. It's a lot.

That is awesome! I'll look into it.
Try Berryman b12 next time
I heard good things about that. I've heard of that and seafoam.
What third world country is this with this type of bush mechanic "fix"? . . .
