I have a 2007 9-3 with the B207R 2.0T. Sometimes when it’s Sitting and I try to start it up, let’s say the following morning or after a 6 hour work day it starts up but then sputters and dies. One time it happened 3 times in a row before it runs. But after it starts up it runs perfectly fine. No CEL or anything. I’ve read about the vacuum pump gasket being bad and it leaks fuel pressure so I try that and I thought it worked for about 5 days but then it happened again.
