Having problems with your 1989 Volvo 240 ?

Car will not start when Mass Air Flow sensor is plugged in; when it is unplugged the car will idle and gradually idle up if you give it very little fuel at a time. Installed a used Mass Air Flow sensor and nothing changed. Any ideas.

Hi there, when air flow unplugged, ecu goes into limp home mode ,a back up if something dies whilst driving. it sounds as if your used mass air flow sensor is faulty , they are more fragile than they look, one knock and these early fine wire models are gone. i replaced many when i worked at a volvo dealership a few years ago. hope this helps, and good luck.
It dont do it for me , maybe someone out there can helpmcloughli234
