how often does the coil go bad? what are the signs, other than lack or irregular spark at start up?

TIA

Coils almost never go bad on ' 02s, but I replaced mine at 280K miles just because a shiny new Bosch blue coil would look a lot nicer after that many years on the old one. My wife's ' 76 still has the original. Remember, new Bosch blue coils are cheap.

It's been said over and over, the blue doesn't perform as well as stock. However, you might not notice the difference.

For actual improvement, use the red coil and a ballast resistor to keep points from burning, or non-points trigger such as Pertronix or other.

because, let's face it, something that CAN go bad, will.

But the parts that sometimes get USED are the spare plug wires. I've had 3 go bad in 15 years of driving- one was the coil wire, and gave up right AFTER a very long, harrowing drive.
