I bought my '02 WRX two months ago, and just recently started smelling a plasticy/rubbery burning smell after a medium high rev (4000 rpms or so). For example, while backing out a friend's steep driveway (moving uphill), I ran the revs a little high as I brought up the clutch. Immediately after, I smelled a burning plasticy smell. It's not burning rubber or oil, and I'm stumped. I've driven standard all my life and never encountered that smell. I doubt it's clutch, but I don't know. Any help? Thanks.
