Yah, sounds like your clutch.
Must be really bad if you can't even stall it. lol.
It's not that hard, pretty much the same as any other front wheel drive car, You gotta remove the transmission, your axle and a motor mount and drop the tranny, and maybe machine your flywheel if your not getting a new one.
Correct me if I'm a little off, I've never done a clutch before by myself.
