I have completed the 4.0L (93 Explorer) swap into my 86 B2. All is well except for a minor drivability issue. Before the engine warmes up the engine has a pulsing or jerking feeling. As soon as the engine temp gage gets up slightly the engine smooths out. It happens every time. Any ideas as to what this could be???
