Doing 65 at about 2100 rpm and 10 psi. I went to pass somebody and the tach hit 2400 and lost all the boost. Now it has no power. Still have 70 miles to home. Anything I can check on the side of the road?
It's a 08 and it does say "cleaning exhaust filter". And it's not cleaning right now.
Go to neutral, shut it off, re-start it and see what happens.
Mine is doing that same thing, on mine it is low fuel rail pressure. Restarting makes it run normal again until it feels like acting up.
