Suspect: Vacuum leak.

Just had air mass meter assembly replaced to cure varying idle (corrected). I still have rough idle that seems as though it is related to vacuum leak. It only idles rough after warming up. Cold start idle is fine. Any suspects for checking vacuum connections. I have Mityvac but not sure of procedure for checking as part of a logical progression.

All help appreciated.

P.S. This is the 300E bought with front end damage. Has been fun bringing back up to snuff. Now looks great and remnant operational gremlins from previous owner's tenure slowly being chased away.
