I am fairly new to driving manual cars and I have never worked on them. My car has started shifting differently (within the past 3 or so months) than it did when I first bought it (2 years ago). When I release the clutch and feather the gas, it seems like the clutch is still partially engaged. The RPMs go up to around 3000 and then slowly drop and you can feel the clutch fully engage. This happens in every gear. Has anyone run across this issue?
