Replying to: fsb (Jun 29, 2008 8:50 pm) 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. Replies to this message: fsb (Jul 03, 2008 3:09 pm) johnv (Jul 07, 2008 5:12 pm) fsb (Jul 07, 2008 6:42 pm)

Replying to: johnv (Jul 03, 2008 1:56 pm) Did you take it into your dealership? If so, what did they say? Replies to this message: johnv (Jul 07, 2008 5:12 pm) fsb (Jul 07, 2008 6:42 pm)

Replying to: fsb (Jul 03, 2008 3:09 pm) 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 Replies to this message: fsb (Jul 07, 2008 6:42 pm)

Replying to: johnv (Jul 07, 2008 5:12 pm) 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).

a TSB was issued that probably fixes this issue. I haven't taken my forester in for this fix as yet.   #11-89-08 Reprogramming Files For High Idle When Clutch is Disengaged http://www.thel7.com/TSB/11-89-08.pdf   Also on a different board, someone reported a similar issue that turned out to be the accelerator pedal position sensor (in an 05 model).

Replying to: fsb (Jun 09, 2008 10:14 pm) Hi there   I drive a 2008 black subaru forester manual base model.   My car did the exact same thing all time and i asked the dealer what was going on. They were unsure at first and told me that they would contact subaru and get to the bottom of it.   I recieved a phone call three days later saying that there was a Re-flash available I drove in the next day had the re-flash done and all was well.   I read the report about disconnecting the battery on here and then the problem came back   i found out that:  WHEN YOU DISCONNECT THE BATTERY IT RESETS THE COMPUTER AND ERASES THE RE-FLASH.   PLEASE IF YOU HAVE HAD THIS RE-FLASH DONE DO NOT DISCONNECT THE BATTERY. OR THEY WILL HAVE TO RE-FLASH IT AGAIN.   Good work and thanks for the advice Replies to this message: paisan (Nov 23, 2009 10:35 pm) leadhead1 (Nov 24, 2009 2:01 am) leadhead1 (Nov 24, 2009 2:03 am) paisan (Nov 24, 2009 5:37 am)

Replying to: leadhead1 (Nov 23, 2009 9:53 pm) Disconnecting after a reflash does not wash out the reflash unless the dealer did not install it correctly.   -mike Subaru Guru and Track Instructor Replies to this message: leadhead1 (Nov 24, 2009 2:01 am) leadhead1 (Nov 24, 2009 2:03 am) paisan (Nov 24, 2009 5:37 am)

Replying to: paisan (Nov 23, 2009 10:35 pm) You will have to understand the system that there are two random access memories. One is for lets say there was a recall and or an emmision concern and the memory had to be re-learnt. The re-flash for this concern is not permanent fix and disconnecting the battery will erase it. I watched the dealer carry out this re-learn and its fool proof that i think that you could even do it.   I phone the technical department for subaru and they even confirmed that this is the case.

Replying to: paisan (Nov 23, 2009 10:35 pm) This is an australian built which has different design capabilities for mapping the ECU please confirm your region before advising so called fixes Replies to this message: paisan (Nov 24, 2009 5:37 am)

Replying to: leadhead1 (Nov 24, 2009 2:03 am) Sorry, I am basing this on USDM spec cars. It would be kind of dumb for the ECU not to keep all the updates to the memory for things like recalls and such when you changed the battery. That would be a major liability for the manufacturers! Hence why when they do flashes like that here in the US they are more or less permanent even if you change the battery.   -mike Subaru Guru and Track Instructor
