WHAT IS MY NEXT STEP IN WORKING THIS PROBLEM OUT? THANK YOU
Those particular engines are EXTREMELY sensitive to vacuum leaks. This is also consistent with your P0174 system bank #2 lean. You need to replace your intake gaskets. They are easy to replace yourself, if you plan on doing the job yourself. Has campaign 00M12 been done on your vehicle? If not, the go to your local Ford dealer parts department, order the kit part # YL2Z-9E473-AA. In this kit, you get upper and lower intake gaskets (which are made out of rubber), updated bank #2 timing chain tensioner, oil pressure restricter & oil gallery plug.

Because you got a misfire on cylinder #1 PO301
A misfire on cylinder #2 PO302
Misfires first 1000 rev PO316
O2 Codes PO 174
The LTT, is the result of not learning (yet-thus long term)
what isn't working correctly---Your Engine
Replace bad Coil--which ever is missing
Do not go by the codes,alone ,TEST
