Yes, it does. It sounds like the same problem. Is your Forester, by any chance, a PZEV?

Thanks for your reply, ateixeira. The dealer wouldn't do it because they said that my car already has the latest version already. I'll have to go back and insist that they re-flash it.

You can still reset the ECU by disconnecting the battery. Disconnect the negative, wait 20 minutes, reconnect.
Have your keyless remote ready and lock and unlock a few cycles to reset the alarm.

I'm not sure that will work though Juice. I think he'll need it to be re-programmed as there is definitely a problem in programing.

Hi ateixeira, I reset the ECU (by disconnecting the battery for 20+ minutes) and got some interesting results. For the first 20 minutes (in surface streets driving), the idle (albeit a bit unstable*) did not bounce between 1000 to 2000 RPM when coasting in gear. However, after that (in freeway driving) the problem came back and is now behaving consistently as before.
*By unstable, I mean that, when coasting in gear, the idle would settle to around 1000 RPM until I took the car out of gear, at which time it would return to normal (about 850 RPM). Same problem but less pronounced.

Yup, 2008 PZEV. I was able to confirm that the revving only happens when I'm in gear (usually 3rd for coasting) with clutch in. Shifting into neutral dropped the rpms to idle.

Did you take it into your dealership? If so, what did they say?

I haven't yet but I'm due for my first oil change so I guess I'll dealer it and ask about the revving too. Have you seen people post about this on any other boards? (It's great to know that I'm not crazy

I haven't seen anyone else post about this problem. I've posted in other boards as well but, so far, you're the only 2008 5-Speed PZEV owner who has replied (with or without the problem).
