You might need a custom tune. Do those codes pop up on the stock tune?

yeah i loaded a custom tune but thought i had blown my engine when i took off. but i guess the tune was wrong. put it back to stock everything fine just still running too rich if i get on it just a lil bit it starts jumping real bad. spark plugs are fine coil packs are fine. maybe o2 sensors?

My car threw those 2 codes, turned out to be my fuel rail pressure sensor. Sometimes it wont throw the P0190 code, but itll say Rich or Lean in Bank 1 & 2
