Hi. First time post. 2 years ago I purchased a manual 2010 Forester. right from the start I found that the engine tends to over rev when changing gear. Instead of the revs dropping , it stays at whatever rpm it was before the change. Also, when crawling in traffic with the clutch depressed (in gear), foot off the accelerator and the car just rolling along, the RPMs rises suddenly to about 2500 then drops down to idle. A few seconds later it does this again. As long as the above conditions are in force it will do this until I put the gear in neutral.or stop completely.
Any ideas??
