Electrical gremlins. Fixed some wires and a new battery, and she runs like a top. Last year I had to buy a new ignition cassette, I had to sputter home from an apostafest. She may be old, but not that hard to troubleshoot.
Now I have to see what is up (pun) with the convertible top that will not go down, probably a prox switch.
Believe it or not, the car is not drafty in the winter. The top is well insulated.
