    It has come to my attention that there shouldn't be a spring behind the plunger on these cars. So if your car doesn't have one, you're good.

      @@donjohnson4368 my suggestion is firstly to check to make sure that the warm control pressure is correct after warm-up. If the control pressure is too low after warm-up the air/fuel mixture will be too rich the whole speed range and that can cause the spark plugs to be flooded with fuel.
