Hey Scotty got the code. P0430. On my Lexus.2002 is300 I dont wanna. Believe it's my cat. But that's. Cuz I wanna save money. Would I start. By. Using laquer thinner in gas tank. Like one of your videos. Or would. I change my 02 sensor. If so which one. There so many on the y pipe. And. Exaust ... Someone said. The Bank 2to2 sensor. .

Ok. I. Trust u more than the people at O'Reilly's and AutoZone they. Laughed when I said. A gallon of laquer thinner. In my gas. Tank they said that's ridiculous.
