My 97 Explorer seems to not have as much power as it did a few years ago when I bought it. It's a 97 with 88,000 miles on it. I've changed the plugs, wires, and installed a K&N filter on it, and cleaned the Mass Airflow Sensor. That still didn't really restore any of the lost power. It seems to run really rough sometimes also. I'm not getting any Check engine light either. What are some things that I should replace? All 4 o2 sensors?
