First of all before anyone can help we need to know what vehicle,what year and what engine.Typically multiple misfire indicates that you need a full tune up,spark plugs,wires etc.If you can’t remember the last time your vehicle had a tuneup then you need one.A tune up is step one to determining the problem,especially when it comes to a drivability issue.
