2000 Ranger 2.5 automatic 4x2 is running so rich it's stalling and fouling spark plugs.It's also pumping black smoke out the tail pipe from idle to about 3000rpm.The codes says it's running lean,but it's far from running lean.The codes I get are P1131 and P0171.Surely a bad O2 sensor wouldn't cause this.
Recent work includes all filter changes,new timing belt with water pump,thermostat,new spark plugs,new spark plug wires,pcv valve,and all vacuum connectors and hoses replace.I also checked to make sure no wiring problems between the harness and O2 sensors.Another note,the truck is all stock.No modifications at all.
