Hi I have a 97 ranger 4.0. It starts and idles fine. But runs horrible when driving. No power runs rough. I had a rich fuel code in the summer when I borrowed a code reader off a friend but it ran fine then so I payed it no mind. My plugs, wires and ignition module are less than 2 years old. I replaced the fuel filter a couple months ago. The cat converter is a after market model about 2 years old and the o2 sensor on the cat is the same age. The upper o2 sensor has not been changed. Well that's the basics can anyone help me. Thanks.
