The first thing you shoulda done was test all sensors, which you said you did and they were in spec and you still replaced them, bad idea, money wasted. Then you shoulda done a complete compression test, not just on the one cylinder. Thus you woulda found that (most likely) your problem requires some engine overhaul. Now go get your hands dirty you 'ford tech'. I sincerely hope you look for work elsewhere (entirely different from the automotive field) considering you are one lazy bastard that I would never let touch my car. Imagine the customer w/ the same problem spending 1000$ or more in labor/parts to only have the same problem occuring. RAWFUL, you are RAWFUL

Just because one works for ford, doesnt make any difference. They have they use of 10's of thousands of dollars worth of equipment,but that doesnt solve the problems for you. Sometimes one has to try everything reasonable in hopes of solving a problem. sometimes it works and sometimes it doesnt,but not even the best tech in the world get it right on the first try..... Before you slam someone, maybe you should put yourself in the same position and then lets see what result you get.....Your idea about his problem was wrong anyway......
Oh and by the way,What do you do for a living?????????
