What would be some symptoms of a bad map sensor?
My truck has been feeling sluggish lately and the cel came on.So I put it on the scanner and it brought up malfunctioning map sensor.So first of all i just went to the junkyard and got a used one but it didn't make a difference and the light came back on.So the truck runs fine at idle,but it just has an occassional misfire out the exhaust.And when I accelerate hard from a stop the truck just feels flat,and no power,it will cruise fine down the road but just sucks the gas and is a gutless wonder right now.So would all this be the cause of a bad or malfunctioning map sensor? Thanks guys.

Use this link to view what the frequency output of the MAP sensor should be: Ford Fuel Injection Manifold Absolute Pressure Sensor (MAP)
You should be able to use a DVM that can also measure frequency to verify if yours is within range.
