Can you help me fix my Ecoboost?
I have a 2012 F150 Ecoboost. To date I have spent approximately $3000.00 trying to fix it. Whenever I step on the gas and try to accelerate with any speed the truck sputters and cuts out, if I continue to push it, it will go into limp mode. I have changed (some) VCT solenoids, Spark Pugs, Coils (some), primary timing belt, both secondary timing belts and all cam phasers with no success. I am at a loss....

Have you checked for fluid in you intercooler? Common problem. Sucks watery oil into the motor from there causing that problem. Lots of people drill a 1/16" hole in it to solve it. I haven't yet because I haven't had problems, but I'm considering it. Search the threads.

Going to take it to the dealer today to get it checked out. I forgot to mention that it works fine as long as you shift it manually before it shifts on its own. One of the codes it was throwing was 0016.
He doesn't think it's water in the inter cooler because it happens consistently even when it's quite dry out....However, that doesn't rule it out. He has an issue with cracked spark plugs too. Is that common??

According to AllData, P0016 means the PCM is seeing a 1-tooth or greater misalignment between the camshaft and crankshaft.
You might take a look at the Ecoboost change[sic] stretch thread on the 2009-2014 Engine subforum.

Sounds like timing is off a tooth. Check base timing again. Check oil pressure. Check wiring for shorts or splices. Do you have access to scan tool that can do live data? Start looking at timing data, seeing what is actually making the vehicle go into limp home mode. Also were the cam phasers changed or not? All or just one side?
Need to see live data. Check other sensors that have to do with timing. IAT, ECT, CMP, TP, and MAF.

I haven't looked at the procedures for replacing the timing chain on the EB (my AllData subscription only includes the 5.0, as that's what I have), but I would think that they would include procedures for making sure the camshafts and crank are in time. Of course, it's possible that he only locked the camshafts when starting the work, assuming that they were in time with the crankshaft, so if they were off a tooth from the crankshaft before the change, they'd still be off a tooth. That seems unlikely, as replacing a timing chain to fix a problem should make a competent mechanic assume that the pre-work timing can't be trusted.
It's also possible that the problem is in the VCT (Variable Cam Timing) system (AllData indicates that the cause could be physical, electrical, or hydraulic), which seems more likely than the camshafts and crankshaft being out of time before and after the timing chain work. Also, you said they changed some of the VCT solenoids; my SWAG is the problem is in the one(s) they didn't change.
