I have owned my 97 Ranger since it was new. It has always lacked power, but it got really bad when the oxygen sensors got dirty. It had severe preignition and no power. I replaced the sensor behind the cat and after the computer adjusted to the change, it ran a lot better. I had the same problem a few years later and after reading through messages on a different forum, I cleaned the Mass Airflow Sensor with CRC Mass Air Flow Sensor Cleaner and after the computer adjusted it ran like I had installed a NEW engine. I have heard that you need to be careful not to spray too close to the MAF sensor because it is easily damaged. Cleaning the MAF sensor every 5000 miles is now a regular maintenance routine for me.
I had also read that the earlier 2.3 liter fours were starved on the intake side and the newer models run better because of a redesigned intake manifold. I had replaced the stock paper air filter with a K&N oiled fabric filter, early on, and it did help the engine breathe, but it may be letting some dust through that ends up as fuzz on my MAF sensor.
