Yes that is what the codes indicate, but what I do not understand is that they would not show at all. But then when I run out of gas, suddenly have these two showing? IF it is a fluke, I would prefer no to have a whole bunch of expensive stuff done (anyone know if it would be) :)

Thank you Steve. Yes I should clarify. I mean petrol. 91 or 94. I looked up the codes before I posted. What I fail to understand is that I had NO engine light on to indicate any issue before I ran out of petrol, then it came on and after plugging in the OBD2 these codes showed up. Surely a Lexus is not that temperamental or lacking solidity? Thanks

Bought my 2001 LS 430 with 82000 miles on the clock. Thought I had enough gas when it read that I had 30 miles left in the tanks, when after 2 miles it was empty :(. Walked to the gas station and filled it with 2 gallons. Engine started up fine, but engine light shows up. Error code P0430 and P0715. Anyone have any idea on how to fix this? Thanks
