So the new BPV did not solve my idle problem. I did some logging yesterday. A/F ratio's are perfectly normal when crusing, at WOT the are at 11:1. Only at idle the fuel trim goes to +25 and A/F is at 17 to 18:1. This morning the car stalled on the first start.

I decided to take all the hoses off last night, in search of a tear (Inlet hoses suck). Long story short, I didn't find a thing. All the vacuum hoses look good as well. What could this be? a tune issue? I don't want to take it to subaru and have them steel my money.
