I recently bought a clean carfax 45k miles 91 stealth turbo that's been maintained really well. Its been running good but when I let someone drive it recently they stalled on a hill a couple times which shook the car. After that incident I have had a strange rattling/squeaky sound when I let out the clutch after shifting (mainly 3rd gear). which sounds like its coming from behind/around the pedals or in the dash area on drivers side. It drives fine but not sure if something came loose? Any idea what that may be?
