Feels like there is some sort of drag on my driveline. Almost like as if the brakes were rubbing, I haven't inspected them yet, but I don't hear any rubbing type noises. Feels close (but not as extreme) to the A/C being on. So what else could it be? If I'm driving on the highway and push in the clutch, it slows down quicker than it should. Also, won't roll down a hill as easily as it should. Killing my gas mileage I bet.
