Trying to pinpoint a problem?

I have a 2008 Aveo LS Sedan the car has decided to have issues first trouble is when I mash the gas to get onto interstate the check engine would start flashing. took it in a had it read It stated I had a misfire on cylinder three. well last weekend I pulled the plugs and found out one was fowled with oil cleaned it off and reinstalled the plug in different cylinder run fine pep was back up now usually during idle it sputters also does it on start up. trying to figure out what is going on and what my next steps would be to find what's wrong.
Second issue is airbag stays on. No clue where to start on that trouble,so it looks like that will be a shop trip.
