Here is some insight and suggestions:
The problem could be the pressure feedback exhaust sensor. They need to be replaced in just about every Ford Ranger eventually.
Disconnect battery for five minutes. Problem should be gone.
Have the DTC (diagnostic trouble code) read with an OBD-ll scan tool by the guys at Auto Zone. It is most likely an emissions issue if there is no driveabilty problem(s) & it's FREE. Have them print you a copy of the code(s). Also, don't throw parts at the problem until you have tested and determined what EXACTLY is wrong. OBD-II is '96 and later vehicles....OBD-I is pre-'96 vehicles.
I have found that it depends on the time of year and where I buy my gas. The check engine light will come on if I buy gas from Shell in the winter. I fill up and at about 3/4 of a tank the light will come on and stay on. Then the next time I fill up at the grocery store gas pump and at 3/4 of a tank the light will go off. It depends on the Brand of gas you Buy and the time of year you buy it. I've had my '96 Ranger since it was new and have noticed this phenomenon regularly. It's something in the gas mixture exhuast that the O2 sensor doesn't like. Just change where you get your gas. Happens to me all the time. No engine damage. '96 Ranger 186,000 + miles, 14 years and still getting 25 mpg on the highway with the 2.3ltr.
