1. Why do the ignition coil packs always go bad?
(besides wear and tear)
2. Since they are common to go bad how many people had to replace them on this forum?
3. I have a 1988 Delta 88 Vin C. I had to change mine twice and it only has 70k on it. The engine in in mint condish.
(besides wear and tear)

Dunno why but I've had to change them on my 86 olds 88, my 1990 olds 88 (right before I totaled it), and on my brother's 1990 Olds 88. Probably all within a couple months of each other.
Oh, and my 90 88 only had 45k on the engine.

i have over 150K and i only replaced once...and i didnt even need to. i just did because i thought it was the cause of a problem i had...turns out the problem i had was just a bad sensor...replaced that and all was good...

Mine never really failed, it just was hard to start when cold. What I found is that resistance of the HV winding when cold was as much as 50k ohms, compared to a standard spec of about 7k. I can only guess that the way this happens is due to a bad connection. Copper does not wear out, but if it breaks then resistance will occur at the break, and I presume when cold copper contracts it must open the gap in the break. Just a mechanical engineer theory about electricity! I have another one based on smoke. Electricity requires smoke to make it work. If you let the smoke out, it does not work any more!
So seriously one would wonder about how these coils are contructed so the copper or solder joints break.
2. Since they are common to go bad how many people had to replace them on this forum?
I've had one 1988 Delta 88 and had to replace the coil at 150,000 km. It was probably failing at 110k but I did not know what the issue was.
3. I have a 1988 Delta 88 Vin C. I had to change mine twice and it only has 70k on it. The engine in in mint condish.
Mine also a 88 Delta 88 C. If one thinks of what an old style single coil looks like, these are very small. One wonders how they made them this small?
