I have a 2009 Lexus 250 IS and I did an OBD scan yesterday and P0335 showed up. The car is driving ok, with no vibrations, hard start, etc. There are no check lights on the dashboard either. I revved the engine to live 5000 rpm the other day and notice black smoke, which I think is a rich burn.
I am curious why there are no check lights on the dashboard and if the rich burn is linked to this code. Please help.
Engine: 2.5 L V6
