I have an intermediate misfire code(P0300). The truck misfires under moderated to heavy load and seems to fall flat on its face, but under zero to light load it runs just fine. It will happen one day then be fine the next. I have already eliminated air and fuel as the problem but I am not sure if it is my coil, distributor or ignition module. I got my scan tool with me but the OBD II port will only let me access codes and clear them, I cant read any active data.
