Assuming HPFP? Guess I'll be stopping by the dealer tomorrow. 69k miles.
Likely, but there are a couple other things that can cause this, including vacuum hose collapse and valve gear issues. It will have thrown a code that tells the dealer what is going on, though. I had the vacuum hose problem once while the car was still in warranty. Same symptoms as yours, traced to crimped hoses.
