I have my check engine light on and the follow codes are being thrown. I just want to make sure they're all related to my no-cats. If I install O2 simulators, it should fix all these, correct?
P0442 - EVAP Emission Control System (Small Leak) Leak Detected
P0420 - Catalyst System, Bank1 Efficiency Below Threshold
P0430 - Catalyst System, Bank 2 Efficiency Below Threshold
P1250 - Fuel Level Too Low
I'm guessing the 1250 might be related to a faulty gas cap I was having at the time, but I'm not sure about that. Anyone know anymore about what that one means?
