P0300 Random misfire
P1201 cylinder 1 misfire, to P1206 cylinder 6 misfire
You have a misfire at all the cylinders, check the sparkplugs for fouling condition or being overly worn condition
other that that to set a P1200 to P1206 , replace the ICM (ignition control module)
Sparkplugs fouling or overly worn will set P1201 to P1206.
