Thanks. I knew the secondaries won't open without a load. I put a clip on the secondary diaphragm shaft then drove for a while. The clip stayed at the top of the shaft.

What is the best way to test an individual plug and ensure that the wire is connected and the plugs is firing? I am assuming I cannot test continuity or resistance with a volt meter since the spark electrode is not electrically connected to ground.

These new E3 plugs don't have a gap to set. They all have probably less than 40 miles on them.
