Intermitant motors should be replaced. From experience, relays and transformers rarely go out. It is usually the motor that burns out and it usually does so quickly when at life's end. Take the time to check all of your wire connections-hours can be spent diagnosing a vacuum only to find out it was a bad connection.ntermitant motors should be replaced.

If a coil goes bad on an old car, it won't run. So you replace the coil, which is usually pretty cheap, and you're on your way. On a newer vehicle, you have 4,6,8 (or 10 or 12) coils to contend with, increasing complexity. I suppose it allows the computer better control, and more energy makes it to the plug. And no plug wires to go bad. I suppose it just isn't cheap owning a car no matter what you have.
