Ok so im tinkering with my roommates 94 (OBS) S-10 Blazer. And without really touching the coil to distribuitor wire falls off, revealing a nice amount of caked copper corroision. Of course my reaction is like, wow i cant believe it still runs lol.

So, i know i can clean up the coil terminal pretty well, but the fact that the wire no longer "locks" on and is corroded to hell, time for new ones?

Thanks,
Mike
