1999 S80 p0300 code S80

My 99 s80 with 193K miles threw a p0300 code yesterday. It had been sitting in my garage for five days in damp weather, and when started, it was really rough for a minute or two. As I backed out of the garage, CEL came on with Emission System Service Required message. P0300 (multi cyl mis fire) was the only code thrown.

I'm assuming this is a result of the rough start, but wondering if it is symptomatic of other potential problems. Plugs were changed at 176K miles, a year ago.
Thanks.
