I have a 1995 5.2l Dakota that has a random misfire while holding a constant speed (same results with overdrive turned off) this developed a few weeks ago. So far i have replaced the spark plugs (RC12YC .035 gap) MSD coil, 8.5mm wires, cap and rotor. I also pulled out the fuel injectors and cleaned them the best I could. (carb and choke cleaner and an air compressor) none of these things seem to have made a noticable difference. The truck also idles well and has good acceleration.
