Couple things starting to tick me off with my car, looking to get some advice
1. Idle is about 900 when engine is warm. Stick the clutch in, RPM's drop to dangerously low levels, causing shudders and sometimes stalling. I've heard anything from a timing belt, to a new clutch to replacing the idle controller, not too sure what to try first.
2. Clutch is getting "stuck". Petal litterally doesn't move after I take it down. Can't shift very easily. Gotta stomp on it repeatedly to get it back up. Could be clutch fluid? New clutch?

Thanks in advance!
