1997 993 Stalling Issue
 

Recently, after driving long enough to warm the car up, it will start stalling when I come to a stop. There are no problems when cold and I recently cleaned the ISV - which needed it badly. Other than the stalling the car runs strong and as you would expect.

Any ideas?

Hi,

How old are the oxysensors?

With a clean and functioning ISV, these do not stall unless there are some vacuum leaks, old primary oxysensors, etc.

Have you disconnected the battery recently?

If so, it will take a while for your car to 'reset' itself.

If that's the case, the only fix is driving it.

Thanks for the ideas. I have not disconnected the battery. I will look for vacuum leaks and check out the O2 sensors.
