My '94 Explorer Sport has been running rough for a while. I have cleaned the MAF sensor, replaced the plugs and wires, replaced the throttle control sensor, the idle control sensor, and I have run lots of cleaner through the fuel system. It is getting better gas mileage than I have seen in years. I checked the codes and it said that both sides of the engine are running lean. That would explain the gas mileage! It runs rough and every so often it backfires up into the intake. It doesn't change when you disconnect the spark plug wire to each cylinder. It smells of sufur, but the there is no back pressure that would indicate a problem with the catalytic converter. Any ideas?
