been fighting this for 12 years some how i seem to pass the smog with several replacments and my scan tool. i some how think the MAP sensor is the problem as i replaced it twice but always with a rebuilt one. one suggestion was to unplug the sensor , i did and the motor still ran great so is this a positive solution as there was no change plugged or unplugged. however i know that can't run the vehicle unplugged forever as codes 113 & 102 appear than have to be cleared. what i'm saying is does this do a positive fix. i spent so much time and money with repair stations & ford and the same codes always come back. buy the way i have the correct LH valve cover and the manifold gaskets have been replaced but never went any further for the isolator bolts and & port cleaning ect. 171&174 always come back.
