Running On Gas

[AFCHH]

I have an 05 RX300 running on LPG. The engine management light and the VSC light are on constantly. Until the computer is used and resets the settings. But the lights come again on after a while. We have this down to the oxygen sensors around the cat and the default setting being too low. Lexus don't want to know. They just want to change everything until I have a completely new car. Does anyone have any ideas?

Yes switch the gas off and run it on petrol like the talented engineers designed it for, mine burnt the valves out twice in 12 months and cost me way more in repairs than I could haver have saved, that is why Lexus dont want to know !

I have a 2001 Rx300 that i had converted to LPG ( multi point system ) my car shows the engine management light & VSC & yes you are corect in your diagnosis of the problem, but unfortunatly i have not found a solution during the past 2years i have been running on LPG, I have decided that i dont really care as i am told that it will not harm the engine & at 57p ltr i love my lexus.
