Cleaning Previa Catalytic Converters With Lacquer Thinner For The Dreaded P0420 Code
Автокөліктер мен көлік құралдары
Our 1994 Previa LE SC AllTrac has been throwning a P0420 Catalytic Converter Effiency code the past several months - and yes, the 1994 Previa does indeed have a functioning OBD2 (Engine Module).
I try out the Scott Kilmer 1 Gallon of Laquer Thinner to 1/2 Tank of Fuel and drive 150 miles at 75 miles per hour to clean the interior of the catalytic converters. You can check out the original Scotty Kilmer video here:

I think the P0420 code is coming from rotting of the 1994 OEM exhaust flex pipe - it definitely has a few small holes that sound terrible under full throttle.
We are taking Floki - the Previa Super Van - on a camping adventure to Taos, New Mexico - throwing on Tiger Patches to see if I can tidy things up a bit as a temporary fix until I can get the Previa into Boulder Muffler for a professional repair.
The Previa might just need a new Flex Pipe, (2) Catalytic Converters, and (2) O2 Sensors.......stay tuned for an update coming soon.....

Scotty Kilmer taught you well my friend :) Glad folks still listens to Scotty. He knows what hes doing
1996 OBDII was required. Roughly half the cars had it in 1995. Some cars models in 1995 had both such as the Mustang 3.8l was obd II but the 5.0l was obd I. Some 1993 Nissans had a OBD II port but I don't know if they worked and followed the protocol. Some cars had both OBD I and II ports depending what system you needed to access like trans, airbag or pcm.
There is different lacquer thinner, automotive is a purer grade used for body shops rather than the store grade stuff.
Ok..First you fix exhaust properly..Then add one gallon L Thinner to 4.5 gallons gas..Clear OBD2 codes/ Erase..Then drive 175 miles roundtrip..Map out gas stations along way..Dont allow the thought that Check Engine Lights turn off by itself..Emergency Mobile Mechanic ASEP Cert...Here to help....

See follow-up video :)
sooo, what is the exact ratio of thinner to gasoline?

Not sure but approximately 1 can (gallon) to a half tank of gas. Mine was a bit more diluted than that at 3/4 tank. Check out the Scotty Kilmer video - that's where I learned about the laquer thinner trick - also 'Herding Cats II' to see how mine turned out. Jamie

Some people do more lacquer less gasoline . Like 1 gallon lacquer thinner to 4 to 5 gallons

1 gallon lacquer thinner to 1/2 tank gasoline - not an exact ratio :)
I watched the whole video for nothing?! Where is the final conclusion…

I updated the End Screen to recommend "Herding Cats II" - thanks again for your input from watching "Herding Cats" on @JamieCars :)
