Cel came on and subsequent diag code revealed p0171/p0174/p0131 codes as does everyone else with similar problems. Replaced isolator bolts, port seals, clamshell seal, 2 other seals, and front valve cover, pcv valve and vac line, and fuel reg vac line. First 2 codes cleared, but misfire remained. Removed intake 2x and cleaned all seals, egr ports, and oil accumulation from inside intake. P0131 code remains. Next step is new spark plugs and wires (only 10,000 miles on new platinum plugs). Also have intermittent abs/brake system lights come on as they wish and go off when vehicle turned off. When is Ford going to step up and admit there is a problem with this entire vehicle ? I will not take my vehicle to a dealership to get ripped off for over $600 when it costs me $120 in parts alone to replace the TSB seals and intake bolts. I guess we shall see how long until my transmission goes out (knock on wood I made over 80,000 miles so far).
