This if in a high resistance state will cause all sorts of weird electrical problems to show up.
I am pretty sure that I took this connection apart and sanded the surfaces and lubed them with grease a few weeks ago when my problem was an intermittent problem and it did not make any difference.
I agree that my problem appears to be, from my experience with cars in general, some kind of connection issue. The low hanging fruit has been checked and now it is more of a concerted check of what part of the car is actually not working. I believe that I have eliminated the Crankshaft Position sensor and the Ignition Control Module as problem sources.
