I started experiencing a misfire during wot a few weeks back. No misfire during idle or casual driving however. Opened the hood and noticed a vacuum hose had come loose. Secured it with a new clamp and drove off thinking the problem was solved but the wot misfire was still there. No cel until a few days later when I got on the throttle a little and it started blinking and stayed on. Scanned and got a cylinder 1 misfire code indicating a bad coil pack as the likely culprit. So my question, would a boost leak cause a coil pack to go bad? How so?

nope

Yeah, I was thinking that it was a coincidence. I posted to make sure. Could a misfire be weather related (temperature wise?) Today was the warmest it's been since I've been having this problem (at least 15 degrees) and earlier when I was driving the misfire was drastically reduced. Tomorrow is supposed to be even warmer so I'll check it out again.

Possibly, but confirming it would not really help with the diagnosis of the problem. The easiest way to rule out the coil pack is to simply move the pack to another cylinder and see if the misfire moves with it or not.
