Default misfire runs rough

my 2005 se neon was running real rough and would hardly accelerate, I put new wires and plugs in and it improved 50% ,head gaskets not blown ,replaced the pcv valve, couldn't find any vacuum leaks, so any ideas would much be appreciated, either maf sensor or oxygen sensor etc etc...………….just put a new map sensor,no change

Instead of throwing parts at it, have you scanned for codes yet?
