I have a1994 Dakota 3.9 v6 that misfires occasionally.I have exchanged all ignition parts with those from a truck with no miss but cannot cure the problem. New wires ,new plugs.new rotor and cap didn't fix the problem.The fuel pressure is about 3 lbs low but doesn't change when the miss occurs.It might miss ten times a day or not do it for a week .It never lasts long enough to identify the cylinder or cylinders involved.Usually occurs just before or just after the 1-2 shift(automatic transmission)Pulling hard like up hill doesn't make it miss. What do I try next?
