what year is your explorer, a 2000? if you use the search bar on this forum, type in your year explorer and "OBDII codes" or something like that, and posts for the code translations will pop up. i dont know what your codes mean off hand, but from the symptoms you are having with your explorer, it sounds as if you have either bad spark plugs, spark plug wires, or both. you could also have a piston misfire, or have oil leaking into the sparkplug tubes which is causing the spark plug wires to short and the codes to pop up. try testing the spark plug wires with a voltometer. test in ohms. youtube how to test spark plug wires for a good explanation on what you should be looking for (inconsistencies in resistance). change your spark plugs and wires for good measure. look to see if there are signs of oil leaking in your spark plug tubes. if so, you will need to replace the valve cover gaskets and spark plug tube seals. also, there are multiple O2 sensors in explorers depending what year you have. these jobs are tedious, but if you guys can do it yourselves, it wont cost much and you will save literally thousands in labor costs a mechanic would charge you. good luck!
