crauch Posted September 24, 2004 Share Posted September 24, 2004 I was working on my parents 99 forester yesterday. They were complaining of the RPM surging up an down from about 1000 RPM down to 500 RPM. It would go up and down almost stalling. They told me they had a mechanic look at it one time when it was acting up before. The mechanic told them he cleaned the mass aif flow sensor. I took it out and sprayed it with brake cleaner. The problem is gone. It beat replacing it for $300 from BAP/GEON or $380 form the dealer. Has anyone else had this problem? Quote Link to comment Share on other sites More sharing options...
sea#3 Posted September 24, 2004 Share Posted September 24, 2004 crauch There is a recall on the Air Flow Sensor on your vehicle, you should check with the dealer . There may be an ECM update as well Get your VIN # and phone it in SEA#3 Quote Link to comment Share on other sites More sharing options...
