Hello guys. My car is an 2000 Acura Integra LS 1.8 L sedan with 81 k miles. My check engine lights up with code PO 172 " system too rich " which is the followed up by misfires on cylinder 1, 3, and 4. Ive taken the car to a shop and the mechanic suggest I need a valve adjustment. He checked all the sensors ( o2, map, maf ) and he said that theyre all ok. He checked the fuel pressure of the pump and its also ok. And Ive also asked a few other mechanics and theyve basically are stuck. Ive installed NJK wires/ plugs , new OEM cap and rotor, etc etc. what do you think could be the problem. pls help me out.
