Dear all,

I need your support

I gave a 2013 Hyundai Sonata

It has a problem that I could not figure although I used a code scanner

The car runs fine but with excessive full consumption .. sometimes the engine will run rough and die .. I replaced the plugs and the coils but no change .. I check the pipes for air leaks but all see fine .. no codes .. Please help me could it be a bad fuel pump or oxygen sensor?

Kind regards
