On my manual transmission gli, the engine stalls intermittently. It has happened at a complete stop, at walking speed, and once around 10mph. It has happened with the clutch pedal completely depressed with the shifter in neutral or in gear, and has also happened while idling in neutral with foot completely off the clutch. It is not a hard stall like learning to drive stick. It just struggles and softly dies out. I have also noticed that the gear indicator will tend to display the wrong gear, particularly when downshifting. I've also noticed that the engine rpms are sometimes affected simply by pushing in and letting out the clutch. I first noticed this parked in my level carport. With the car in neutral, pushing in and letting the clutch out will result in a brief slight rpm spike. On other occasions it is completely absent like normal operation. I classified this as power train, but it could be engine, transmission, computer management, etc.
