Sounds like you're losing the engine vacuum that holds the vents open
(Volvo used vacuum solenoids to open/close the floor, windshield and
recirculation vents in the 240s). Replace the check valve on the intake
(it's the one that sticks up from the intake runner #4, the one closest
to the firewall). It might also be the vacuum bottle that it connects
to leaking or a hose being off or cracked on the interior ventilation
system, but those would also cause a rough/searching idle. I've never
had to replace an interior component but have replaced the check valve
in many 240s.
