The idle of my 2008 Forester oscillates (between 1000 and 2000 RPM) indefinitely when I push in the clutch with the transmission still in gear. As soon as I take the car out of gear, the idle drops back to normal. I took the car to the dealership who was able to reproduce the problem but, because they didn't have a fix for it, their answer was that the car is behaving as designed. The service advisor more simply described it as a design flaw. I wonder if anyone else has the same problem and if they've had better luck getting it resolved.
