New parts = bonus! Plus they replaced the water pump, so you should be G2G for a while.

Hi. I bought a 2016 sho and have been experiencing basically the same problems. My car is currently at the dealership here in Maine Prime Ford of Saco. The have been diagnosing it to be air/fuel related and has replaced the following: Removed CAI replaced with stock air box, plugs, Fuel pump, Fuel line from HPFP to fuel rail, MAP sensor, O2 sensor Bank 1 stuck rich, PCV valve, Fuel Rail is on the way currently to be replaced with 3 fuel injectors. So far my bill is $5500 and apparently none of this is covered through my warranty. Everytime at WOT car goes limp. Its been a nightmare. I know my warranty will cover power terrain. Any suggestions is much appreciated. I know its a little late since its been at the shop for a month but nothing they have done has fixed the issue and I cant think paying 5500 for basically nothing is reasonable at all.

Do a compression test first, make sure the engine is healthy.

Clean both MAP sensors and the IAT sensor with MAF sensor cleaner.

F150 ecoboost fixes do not necessarily translate to SHO fixes. First confirm there IS a problem to be addressed. Jack up the car on the driver side, remove the IC to TB hose. After about 10-15 minutes, use the engine oil dipstick to check the level of accumulation in the intercooler. If it is under 1/4 inch, unlikely to be an issue, though it should be sucked out anyway, so you might want to have tooling available to do that. Look to ecoboostperformanceforum.com, HOW TO section for ideas on this procedure.

You will at some point want to borescope the back of the intake valves to see if there is carbon buildup that needs to be addressed. At the mileage stated, should not be an issue, but ... A carbon issue likely goes along with buildup in the intercooler.

Are you using a quality full synthetic 5W30 engine oil?

Is the battery good? Not just voltage, but CCAs.

Are the misfires felt only at speed, while accelerating hard, or all the time/any time?

Also please post pics of the engine bay, intrepid members will spot if there looks to be anything not OEM/out of the ordinary that might be contributing to the

Did they figure it out I’m in the same exact boat with 55k
