Suggestion

Some couple of years ago to I tried running a bottle or two of Techron through the gas tank (and changing the oil afterwards) and switching to and running a name brand/top tier gas (Shell mainly) instead of Rotten Robbie or USA gas and the check engine light stayed off for quite some time.

As bad as I'd like to resurrect both my car's converters (P0430 and P0420) I'm not about to run lacquer thinner through the gas tank.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

First time I've seen this. Basically he suggests mixing lacquer thinner into the gas tank!! Or remove the cat and wash the internal with soupy water. Really??? http://www.youtube.com/watch?v=5icTmYItwiE

POST 2Original post

I just have dogs. Any cat that comes in my yard doesn't last long. That said the best way to wash a cat is to fill a trash can about half full with soapy water. Throw the cat in and slam the lid on. Let the cat thrash around for a couple of minutes. Tip the can over and get the he'll out of the way. Don't do this indoors.

POST 4Original post

Ummm, no. As bad as I'd like to resurrect both my car's converters (P0430 and P0420) I'm not about to run lacquer thinner through the gas tank. I recently saw one converter off the engine and I peered inside the converter and saw no sign there was anything in the converter that soapy water would remove. Some couple of years ago to I tried running a bottle or two of Techron through the gas tank (and changing the oil afterwards) and switching to and running a name brand/top tier gas (Shell mainly) instead of Rotten Robbie or USA gas and the check engine light stayed off for quite some time. But over this last winter and even until now (just yesterday as a matter of fact) the check engine light is back on and I can tell from the way it glows it is a P0430 error code. The converters are simply wearing out, after only 243K+ miles. They just don't make converters like they used to... Sincerely, Macster.

Quotes source post: 8643525

I guess nothing to complain if my cat (or any other parts of the car) fail after 243K miles!! Yea, I'm very skeiptical whether washing it will work too. Pouring thinner is way too risky for sure.

Sorry to hijack. I just couldn't resist.

POST 9Original post

Not willing to try lacquer thinner in my 996 engine. I need to replace my left rear cat on my 2001 996-looking for a used cat somewhere-any leads? Apparently must be from a 1999-2001 model only, not 2002 or above. NJ inspection due next month. Thanks Jim Moore
