Engine misfires & judders at 3000 rpm

The car is a SAAB 9000 CD 2.0i 1989. LH 2.2 system (not fitted with di cartridge).
Whenever the revs hit 3000rpm the "check engine" light will flash and the engine starts to misfire and judder. Switch off the ignition and restart seems to clear it but again once 3000rpm is reached the fault appears. Fitting another air mass meter from a breakers yard has fixed the problem but it reappears again after a few weeks (or if lucky 2 or 3 months). I don't know if something is causing the air mass meter to malfunction or the fault lies elsewhere. Grateful for any advice.
