Idle relearn procedure

SOURCE: Cause of noise in front differential of 1997 Subaru Legacy Outback.

there is a plug on the shaft-side of the differential. Using a ratchet remove the plug and with the engine OFF, stick your finger inside the hole and you should get fluid just below the threads of where the plug goes in.

If I am correct the po170 code is a lean condition. Usually this is caused by a cracked air duct leading to the air filter. Or the air filter box is not secured properly. I work in the service department at subaru and when we do big services we dont get the air box on right and customers return with a check engine light with the same code and we always find that the air box is not secured. This does not mean this is the issue, for a fuel trim code could be other issues, but I would definately look at this first before getting into a/f sensors, converters and all those other expensove items.
