I'm having the same problem with pinging with my wife's 01 Outback 2.5L. It has gotten worse since the weather is above 70degrees. I just dumped a bottle of Techron into the tank. We will see if that helps. I imagine it is due to carbon buildup (Effectively increasing the compression ratio of the engine) since she does only stop and go driving in city traffic with lots of idling. Noel

Just for others info. I had a heck of a time getting the correct rotors for both my 1996 Legacy LS Wagon and my 2001 Outback. I got them from Advanced Auto and AutoZone and no one seems to have the correct size, even though their system says they fit. Just a word to the wise to measure the diameter of your old rotors and compare them to the replacements before you take everything apart. I ended up going to the dealer for the parts. Noel
