1. Yes. The relay was mounted on the strut tower and had no air flow over it. Probably why it popped.
2.Yes. I set IDle speed several times during break in.
3. Yes. Timing was set @ start up and 2 times, checked after.

Most fuses aren't designed to be air cooled, if it popped it was most likely the result of too much current going through that fuse/relay.
