If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.Google+

Losing power on acceleration.
I had to replace the starter because it stalled me at the clinic. The oil was dripping down in the starter. It's hard to start my Taurus in the cold. While driving it feels like someone is rear ending me. The transmission bumps. When I turn my car off it has a faint clicking under the hood. I've never been sent anything for recalls before. My email address is email@example.com

PVC Valve warn to the point of wide open at idle and acceleration. Look and see of it is close air off or it will effect IAB valve.
