Hi there, I've done a couple of searches but I'm really stuck as to what's making my lovely Saab 9-5 2-0t Automatic (2004) stall when brakes are applied.
My first notion was that the Cranckshaft Position Sensor was screwed (again), but the symptoms are different this time around.
The symptoms:
- Shifter is in "Park"; engine will not start unless I apply a little gas.
- Engine runs fine when started, but as soon as I apply the brakes the engines rpm drops until it stalls.
While looking around in the engine bay I notice that:
If I disconnect the vacuum line the engine runs fine, I can apply brakes and the engine does not stall. As so as I connect the vacuum lines the engine stall (if it's in idle and brake is applied). I've supplied a couple of pictures to show which vacuum line I disconnected.
Any suggestions as to what could be the main issue would be greatly appreciated!!!
