I have a 1995 Dodge Dakota V8, that while driving down the highway, it spits and sputters and looses power. It will drop down from 65 to below 50 mph or lower with the pedal all the way down. It will do this one day, and then it will happen again any where from 1 day later to 3 weeks, or 3 months later. I have replaced the wires, plugs, distributer cap, rotor, pickup coil, ignition coil, crank sensor, and catalytic convertor. What do you think is causing the problem?
