Alright so before anyone says it, I already tried searching the forums and google for an answer. But I didn't find anything where someone had the same problem as me. So that is why I am here

I have a 95 Integra. GSR Trans, ACT 6 puck, stock slave, stock master, stock lines.

I was going on a drive. Everything was normal. Pull out from a stop light. 1st gear, good. 2nd gear, good. 3rd gear, goes in, go to let the clutch out..clutch pedal stays stuck to floor BUT the vehicle is still in gear, not in neutral. So I limped it to the closest gas station. Pulled out on the pedal. And everything acted normal. Check fluid, lines, everything. All seemed fine.

What the hell caused this? any ideas? I'm stumped.

 

Most likely a bad Clutch Master Cylinder or possibly a bad slave cylinder. Instead of pushing the fluid to push the clutch, a small tear in the piston seal in the master cylinder is intermittently allowing fluid to bypass the piston instead of moving through the line and operating the clutch. Then because there is no pressure in the line to push the piston back and in turn push the pedal back up, the pedal remains stuck on the floor until you pull it up.
