I have change the computer and after that I took a ride and the car did not buck.

Two days later it stopped completely.  I looked at the ignition switch and found the plug be only halfway on it.  Tried to push it on better but it would not go at any rate.  Puzzled, tried again and again, than layed down on my back to take a look.  One of the tabs were bent and would only enter the plug but would not slide in, making a slight contact only but intermittent perhaps.  
I straightened it and the plug went in fully.  It started and there is no problem since.
This can be put on the "bucking list".  Any of you had the same before?
