Just returned from a Costco run and at the 3rd last set of lights before home, the clutch depressed to the floor normally, but then just stayed there! After pissing off a line of cars behind me for about 5 min, I found that I could pull the clutch off the floor manually and then the spring would kick in and return it to the normal position. If I fully depressed it again - it would stick again. I was able to limp home by only pushing the pedal 3/4 of the way in - enough to be able to change gears - and the pedal would spring back. My first thought was, of course, the floor mat, but that wasn't even close to it. Any clues? Master Cyl? 2002 Accord EX-L 75,000 km a
