From www.dtcdecode.com, those are Over Advanced Camshaft Position for banks 1 and 2 on Cold Start. Not sure of the strategy on that engine management system, but I would not think the cam position sensors are both bad. The system is receiving some information that makes it think the cams are over advanced (possibly a temperature sensor). Check for TSBs relating to that issue at a FORD dealer or subscribe to a service such as www.Alldatadiy.com or Mitchell's www.eautorepair.net . These web sits are well worth the cost, which is under $50.00 for a year's subscription. Hope this will get you going in the right direction. Good luck and let us know what you find.
I would be suspicious of the starter itself. Metal shrinks and expands as it gets cold or hot and all metals do so at different rates. My suspicion is that something inside your starter is doing that. Applying extra power ( boosting) is compensating by providing extra juice to bridge the gap and start the vehicle. Double check the wiring at the starter but if all the wires are tight then I would replace the starter. Hope this helps.
REPLACE AIR FILTER.STOPPED UP AIR FILTER FILL EFFECT TURBO CHARGE PERFORMANCE.22 PSI IS OVER BOOSTING.CHECK VACUUM HOSE GOING TO WASTEGATE SOLENOID.MAKE VACUUM IS GETTING TO SOLENOID.IF GETTING VACUUM HAVE WASTE GATE CONTROL ROD ADJUSTED.THATS WHY YOU GETTING OVER BOOST.
you probably need new turbo. check oil supply to the turbo. grinding noise sounds like bearings in turbo are overheating do to lack of oil and slowing down the turbo. that explains the uneven boost press.
