I am having issues when driving my truck, around 45-50 mph, it feels like someone grabbed the driveshaft and let go really quick (no other way to think to explain it). I have a P0341 code showing up but i have changed several sensors including the camshaft position sensor, crankshaft position sensor. I pulled the # 3 plug wire off the distributor today and noticed some rust residue. I had just replaced the distributor cap and rotor button in the last few months. I was having the driving issue before and after the distributor cap replacement. Not sure what to do to get it fixed. Could it be the actual distributor itself?
You need to check the wires between the cam sensor and the PCM. Tug on the wires right at the connectors to see if any pull out or stretch. Use an ohm meter to check resistance continuity on each wire between sensor and PCM while moving harnesses around to see if the meter goes OPEN. If can sensor is good, wiring is good, then most likely a bad PCM.
