I've been driving my 2012 wrx for 2 months now and this was my first stick shift car. It's got 37k miles. When I'm in 3rd, 4th, and sometimes second gear, if I give it a decent amount of gas, the rpms will go up fast, like if I was in first hear flooring it and my speed doesn't go as fast as it sounds like. I don't have my foot near the clutch and a few moments later, It smells like burning clutch. Is my clutch going bad? Or should I just downshift and slowly accelerate?
