With 128,000 miles my car has been running exceptionally well recently. But, for the past 5 days it has been losing boost. What I mean is, it starts normally and accelerates like the proverbial scalded cat, but about 3 minutes in...no boost.
It isn't going into limp home mode, it does kick down...just no turbo.
Stop and restart the car it's back to normal.
No smoke or anything.
First thoughts?
