My 1984 Rabbit Convertible runs great, but has a surge in idling and after driving for a short while when going to stop, stalls out?

I believe it is a vacuum leak. I have replaced all the hoses from the vacuum advance up to the TB. Still surges when warmed up and will stall unless I keep my foot on gas a little.

You are right it is a air leak but either at the intake gasket or tb gasket seeing you replaced the hoses already. spray some carb cleaner around those areas while running and see if idle changes this will pin point the area of trouble. make sure you dont have any spark plug wires arcing out cause this could ignite the carb cleaner.

Testimonial: "I believe my CIS needs adjusting, the engine was checked thoroughly for vacuum leaks. We came out to Denver recently from North Carolina in the Rabbit. I believe the altitude has something to do with it. Thanks for your input though, believe me if there is anything else I will be back to ask another question!"

Low idle stalls out
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
