Thanks for writing in about your 2006 Ford Five Hundred. Your vehicle uses the barometric sensor, along with other sensors, to determine the engine load. Your barometric sensor should read a vacuum at idle. With the ECM having conflicting information, it may be defaulting to a safe speed. There are several things that can cause false sensor readings. I recommend having a certified technician, like one from YourMechanic, inspect the acceleration issue in person in order to have this resolved.
