97 Catera misfire

Wife was driving home tonight and the engine started running rough and check engine light came on. I read the codes when I got home: P0301 misfire on cyl 1.
Runs rough enough I plan to check compression on that cylinder tomorrow to check for valve problem. Could a bad injector cause problem? A bad coil would misfire on two cylinders right? Any suggestions?:hmm:

it is cake to get to the coil pack without removing the windshield wiper motor. It takes me 30 minutes tops now a days after replacing the damn thing so much.

BTW be forewarnded

if #1 went out it was more than likely due to oil in the spark plug galley. This forsaken coil packs do not withstand getting sent to ground at all. (went to three going on four).
