This is for a friend of mine. When he turns the car off, just before it completly stops it will fire back up for 1/2 sec. Just like 2-3 more rotations. Could this be from the timing belt?

PS: it is a porsche 944. I believe it should run on 92 octane.

 

Don't they all do that?

try a porche board

 

I got a 924. That sound like the timing is off. Get a timing light and adjust the timing!
