My 97 Z24 backfires like crazy!!?

I got a code for p0300 random misfire. Could it be the Ignition Coils or Coil cover(what gm part dealer calls the battleship)? i have new plugs and the coil adapters. Also i was wondering could a malfunctioning knock sensor cause a misfire

Yes, that is a common cause to the p0300 code on that car. I happened on my first car years ago - ended up changing the ignition coil, plugs, and fuel filter for good measure. Problem resolved.
