    Check your warranty, if I remember correctly the emission control system has a long warranty like six or seven years. If so get it back to Toyota.

    Around $26,000 worth of unleaded in the fuel tank.
    Try cleaning the cats before you spend hundreds for new ones.

    Theres no way to clean out the cats. If the turck is throwing cat codes then the only thing to do is replace them. Toyota does have a longer warranty on cats so it wouldnt be a bad idea to look into that. But if your going to replace them then I suggest only toyota factory parts and not aftermarket ones because they never last.

    Thats a clean cat. lol

    Detergent, enzymes or citric acid can be used to clean a cat. The material inside gets coated with greasy soot and it reduces it's efficiency. As long as the material is not melted, it can be cleaned out.

    This cat is clogged. Remove the offending particles, and it will work again.

    It might be... it's been a LOOOONG time.

    I had an emissions issue on my '91 Ford Escort at about 65k back in '94 and the dealer fixed it saying they had to fix it up to 70k.

    Cats are very sensitive. An engine running too rich or misfiring too bad can cause then cats to quit working or even melt so cleaning them our with a detergent or paint any other substance is a really bad idea and will only make things worse. And the dude in that video has got to be hitting the pipe. I would absolutely never pour paint thinner in my gas tank ever! talk about damage to injectors or other fuel components.

    Yeah the laquer thinner through the tank is likely harmful to injector seals and other rubber parts. It would probably burn off before reaching the catalytic.

    Catalytics have platinum inside which is a hard metal, and besides why would you care if it got destroyed if you were gonna replace it anyhow? The platinum is harder than the sludge, sulfur and unburned fuel additives that become stuck to it.

    Cleaning it is worth a try. For some reason people are against the idea. :washing: So go out there and put yer cat in the washer!
