Have you ever tried to fix a problem, and it only seems to make matters worse? We had just such an experience with a 1983 Audi Quattro Turbo. The Quattro’s ignition system was only sending spark to four out of the engine’s five cylinders. Just when we thought we had the problem licked, the engine decided that it would really rather not run at all. Apparently it had gotten used to running on four cylinders and had decided that it like it better than firing all five cylinders. Four cylinders or no cylinders – your choice.
