Misfiring Issue(s)
Hey guys, hoping y'all can help because me and my uncle are out of ideas. 97' Dodge Dakota sport, a little over 100k miles. It was throwing a 303 code for a misfire on cylinder 3. We changed the distributor cap/rotor, plugs, wires, etc. full tune up. Check engine light comes back on and the rumble from misfire is fairly consistently bad. When we unplug the sensors and/or reset the battery, it'll run good (no check engine light) for a couple hours but inevitably, misfire resumes. We checked it again yesterday and it was now saying misfire on cylinder 1 (which it never has previously) and cylinder 3 but we can feel ticking at the valves. It seems to be electrical like a sensor is saying there's an issue when there isn't and causing the ECU to make changes/adjustments that aren't necessary and causing the problem.
Has anyone dealt with this or have any ideas? I'd really appreciate any help.
