That is funny you brought up the CAT issue. I am assuming you mean the catalytic converters.
They were plugged on our problem child, but that made the car not start. These are very expensive. I am now
going to suggest you find a Lexus dealer in your area that has Elite status. That is very important. If you cannot find an Elite Dealer, You are going to need a dealer tech that understands a thing called Fuel Trim.
This will lead to a fix. I am sorry I cannot be more helpful
at this point. I recommend a dealer tech because they will understand the fuel trim numbers better than a non dealer tech. One thing, if you got water with that bad gas, unless the fuel tank is completely drained, and cleaned, that water will stay in the bottom of the tank.
Water is heavier that gasoline and will stay at the very bottom of the tank.
The fuel trim values are the key here.
