k9sar Posted March 15, 2011 Share Posted March 15, 2011 is that the order they were in? I think this is right (though I don't have an R50) P0463 Fuel Level Sensor P0182 Fuel Tank Temperature Sensor P0174 Fuel System Lean, Bank 2 P0420 TW (Two-Way) Catalyst System, Bank 1 Link to comment Share on other sites More sharing options...
Towncivilian Posted March 15, 2011 Share Posted March 15, 2011 Try changing your fuel filter and running some fuel injector cleaner to see if that clears anything up perhaps? Link to comment Share on other sites More sharing options...

Towncivilian Posted March 17, 2011 Share Posted March 17, 2011 (edited) Check fuel lines, make sure they're not cracked or worn. Is your gas gauge accurate? Sure it's not a bad batch of gas? Try getting some gas from a different station, and run some 91 octane fuel for a few tanks. Edited March 17, 2011 by Towncivilian Link to comment Share on other sites More sharing options...
adamzan Posted March 17, 2011 Share Posted March 17, 2011 Well since it's an 03 with the 3.5L you're supposed to run 91 octane all the time, but I don't think not doing it would cause the SES light to come on. Sounds like you have a bad 02 sensor and maybe fuel gauge sending unit Link to comment Share on other sites More sharing options...
