Multiple codes where to start

[MRBLawnguy]

We have a 2019 Fiesta SE with codes p2112 throttle actuator control system stuck closed, p0351 p0352 ignition coil A/B (all 4 ignition coils replaced yet the code comes back), and p0011 A camshaft position timing over-advanced or system performance bank 1. Symptoms are stalling, loss of power, no start randomly, rough idle, idles down and almost dies. I do get live data to my scanner from the ecm. I just find it odd to get all of these at the same time so I am thinking it is bigger than just replace the throttlebody, vvt solenoid and coils. Any ideas?

You may also have something more catastrophic - besides the codes. May be engine related down at the Crankshaft Sprocket that turns the belt.

Or, something got sucked into the motor thru the throttle and it's grinding away inside...

You may also have something (addition to or otherwise possible cause). An item that may have struck or got wrapped up into the serpentine belt - which then launched a cascade event of breaking wires or scuffing harnesses - doing some internal damage to the wiring.

Not often does the throttle body fail unless its a foreign object, it's internal toothed gearbox breaking issue or wiring...

You may have to remove the throttle body and disassemble it to verify the gears are intact and no damage...

Have you checked the spark plugs? Take them out and use a drop camera to inspect the combustion chamber, make sure they are clean and the valves are not stuck open or bent, by debris...

I fear it is more catastrophic at this point. I went ahead and replaced igniton coils and spark plugs since it was time. That was the first code that popped up. The rough idle improved but that was it.
The wiring seems to be good checked grounds and voltage on most of the sensors.
