Have a CEL, plug in the obd2, have 7 codes. I can't win. Basically it's a cylinder one and three misfire, random misfire, and a PO420 cat converter code. I changed the spark plug, spark boot, injector on cylinder one. I'm thinking fuel filter next and cat converter. Any help would be appreciated. |

P0420 Catalytic converter system, bank 1 - efficiency below threshold Possible causes;Catalytic converter, wiring, HO2S 2 3.7 Bank 1 Sensor 2 refers to the drivers side sensor behind the CAT The fuel filter is built into the pump inside the tank. You could also pull the EGR valve and clean it. |
