ECM went t*ts up. My '02 did this exact thing. Assuming I interpreted your post right....not even touching the skinny pedal..it just revs by itself.

Find a buddy or a salvage with a comparable ECM and swap it. It will take you 15 minutes to swap and start it up. I'd bet this solves your trouble. It is worth 15 minutes to try to end your agony.
