2008 cvpi hestitates n makes a quick n short, card shuffle/flutter sound at Wot.

What is your question?

Does it at low speeds. Just pauses right after a quick throttle stomp makes a 1 sec. fluttering air type noise when it takes off. I do have a oil leak onto the manifold in the rear of engine I believe. Only smells when at stop and leaves no drips on driveway. Transmission has a ford inline filter that always has a drip of tr. fluid on it but never on driveway too. Those are the only leaks I know of. What do you think? Runs fine other than that

What makes this problem better or worse?

Warming it up

How long has your 2008 Ford Crown Victoria had this problem?
