I was driving my '11 WRX (non STi) to work this morning. After it warmed up (temp between C and H), I noticed that when I press the clutch fully, the engine rpm drops to about 2000, vs the 1000something/whatever lower value it idles at. Consider the scenario: Let's say I am in 2nd, going 40 and want to slow down. I press the brake, put down the clutch, and slow down to 10 or so via brake. Clutch down, rpm is still around 2k...I let it out slightly, the friction lowers the rpm. I push clutch back down, rpm stays same...ie, the rpm for some reason stays around 2k unless I use the clutch to bring it down. This does not happen all the time, but I have noticed it a number of times and was wondering how normal this was. I am new to driving a manual car, hence I ask...
