Auto choke on a 911 porsche 1980SC not working

My Porsche 1980 SC 911 used to when started automatically rev up and down after starting. It was as though I was placing my foot on and off the accelerator reving the motor for 30 secs to a minute then the motor would settle and idle normally. This function has stopped and I now have to start it usually 3 times until it settles. I need to understand what has gone wrong.

Besides a leak on intake I will check the ECU just to make sure that thing is working as it was intended to, a sitting car usually have moisture build up and is not friendly with electronic components.

1980 Porsche 911SC Problem #1. Cuts out on freeway, then engine will start again after between five seconds and a minute Problem #2. After parking for a short while the engine will start, but dies...

Check for a intake hose leak between your mass air flow sensor and the intake manifold. Porsche refers to this piece as a vane air flow sensor.
