Robert-

Have you checked your prlug wires?  You know... 3 to 3, 4 to 4, etc.  I
had similar problems with mine and couldn't figure out what was going
on.  I checked and found I had reversed 1 and 3 wires.  When I plugged
them in correctly, it worked like a charm...

I've also had a problem on my truck; I had the dist. 180 degrees out and
caused the same problems.
