Answer 1

P0300 Random misfire

P0304 Misfire number 4 cylinder

You should not drive with a misfire code, on MBZ a misfire the ECM  shuts down that fuel injector to that cylinder,it does this to protect the catalytic.The performance will be slugish for a simple misfire and there the possibility you will make the repair even worst
