I am planning on that as a first priority, but am also thinking of getting rid of the secondary's. I am still learning these engines, but I thought running the car in the "normal" position kept them from opening? and wouldn't cause the misfire???

A vacuum leak is a vacuum leak. Keeping the secondaries "closed" doesn't seal it.

Thanks, thought maybe it was on its own sealed system. I did inspect the vacuum lines when I had the plenum off and everything looked good. There was a two wire connector near the center under the plenum that wasn't connected to anything and there was nothing for it to connect to. Any idea what this is?

Wasn't there a solenoid just in front of the coil packs that had hoses connected to it? Maybe post a pic of the connector.
