Hi guys. This is my first post to this group.
I own a 1998 Subaru Forrester which has never given me a day of trouble until last week. It would just die intermeddiately with no warning. The car doen't miss or run ragged. It will run for 2 minutes or 2 hours and then just die. All I have to do is let it sit for 5 minutes and then it will start again like nothing happened. The "AT fluid at temperature" indicator will come on when the car stops, and sometimes stay on for a few minutes after it is running again, but that will turn off.
I took it to my local mechanic and after testing everything he said it was the Mass Air Flow Sensor (he checked the Main Relay which is fine and the ECM.
He wants me to buy a Mass Air Flow Meter (the AFM which is MUCH more expensive). I asked him if I could just buy the AFS as that is a quarter of the price. He said it's very difficult to install the AFS into the AFM assembly.
But is it REALLY that difficult to replace the Air Flow Sensor? I'm not terribly handy but as these components are right there on the top of the engine I'm just not sure why it would be so much work.
So my basic question is "how difficult is it to replace just the Mass Air Flow Sensor on a 1998 Subaru Forrester non-turbo". The air flow sensor kinf of looks like a Pez dispensor with a flang on top for mounting and a four wire connection harness port.
Any advice would be appreciated, thank you!!!
