Hi Scotty! I have a 2000 Ford Explorer with 173000 miles. Its been running funky, loss of power going up a hill, misfire, feels like engine choking. A friend replaced the O2 sensors and a couple weeks later the battery died with no warning. I have had the oil changed, replaced the battery, and a mechanic replaced the #4 spark plug, ignition wires, coil pack and fuel filter. It still has a miss, leads to PCM although it does seem to have more power when I drive it. I don't want to soak a lot of money into a car this old, but don't enjoy walking to work. Got any ideas?
when that old, it's often best to live with minor problems on an old explorer rather than throw money into an endless pit. But do try this video,https://www.youtube.com/watch?v=cP7D-5iQcNo&t=37s
