Disturbing Clutch Problem
Ok, here's one I've never heard of before outside of cable clutches.
This started last night, and within a few hours of driving around town escalated to being a frequent problem. When I start letting off the gas in preparation to shift or coast, every now and then the clutch will pull itself to the floor. On its own, with no effort on my part (just making that clear). Beyond that being strange, the bad part is the engine will still be engaged with the clutch. If I stick my toe under it and lift, the clutch pops back up into the normal position, and works normally when I stomp it back down.
So clutch pedal goes down on its own, and the engine stays engaged with transmission until I lift the pedal and push it back down, at which point the clutch disengages.
I've heard of broken pressure plate springs pulling a cable clutch when the torque reverses, but this is hydrolic. Pulling the system from the wrong side should just draw fluid from the cylinder tank, not draw in the pedal. I've already ordered new rebuild kits for the master and slave, but a leaking system shouldn't be pulling the pedal down either, just make depressing it work to less or no effect. And this is more than annoying, it's a bit dangerous: I was pulling up to a traffic light in 1st just after getting on the road, and went to hit the clutch to pop it in neutral, only to find it already down and the transmission torque not wanting to release the gear without it. Having a little more horsepower than a normal FC, it almost dragged me into the intersection before I mashed the brake and stalled the car out.
Any ideas about this phantom weirdness?

I think I like that answer the best. Further evidence of possession would be the oddly specific times she decides to grab me with the seatbelt lock...
Did a complete flush of the system while waiting for the new parts to come in. It definitely made a difference. Shortly after the writing, I left the clutch fall and then intentionally stalled the car, had a second person get in the seat and lift the clutch by hand while I watched the TO arm -- thing didn't budge a millimeter when the clutch came up, so it wasn't anything to do with the actual clutch mechanics. Probably just a worn out cylinder seal intermittantly gapping; soon to be replaced when life gives me five minutes to breathe.
