My 1992 Passat is unfortunately a California emissions vehicle while I live in the far north. My car stalls at stops. If I disengage clutch, i can manage idle and car doesn’t stall. Happens hot or cold. Car was removed from ten years storage and brought back to life two years ago. Most everything was replaced. Rear main/flywheel/clutch assembly/master and slave cylinders all new. Transaxle rebuilt. Help!
