My problem ended up being 2 bad coils #5 & #6. It threw a misfire code one day so I ended up replacing all 10 plugs and coils and the thing runs great now. I found new Motorcraft OEM coils on ebay for about 25% of what they cost at the dealer.

I still have no idea why it threw a po720 code (output shaft speed sensor).

thanks it's fixed #9 coil

mine had #9 missfire fault before the p0720 crap so i replaced all the plugs cleared the fault it was fine till today started it up put it in drive and engine was running rough and the O/D light was flashing died out and threw the p0720 but no missfire faults so for the hell of it i unpluged #9 coil and injector put it in drive and it didn't die out, so i threw a new coil in and it's fixed

that p0720 must set when it goes into limp mode or somthing
