The ac fluid(gas ) never gets old as it is a gas . The oil never oxidises as there is no air in the system so it never needs replacing. Most problems with ac units come from leaks and owner interference ( replacing gas that doesn't need replacing) or over filling with the wrong gas or just not understanding how and why it all works.

PO171 and P1131 point to lean codes on bank PO174 and P1151 point to lean code on bank PO305 is missfire on cyl 5

the lean codes is probably a vacuum leak or maybe a MAF sensor is bad or dirty

missfire is dependant on engine if a V10 it may be a coil actually pretty likely on the modulars not uncommon thats for sure
sorry forgot to add that its says missfire on #5 cant remember if that one is the first on the left or last on the left facing the engine vacummn leak could be those dang auto hubs got it stuck in the mud and they did not engage I need to buy some new ones took them apart to clean them out this summer

My guess would be dirty fuel tank. Possibly clogged fuel pump strainer.

P1451 means EVAP-vent valve circuit malfunction.Did you check wiring?

Follow the upper radiator hose to where it meets with the engine block.
Where it attaches, is the thermostat housing. Should have 3 bolts on it. The thermostat is underneath the housing.

have you check the spark plus or lead if ok check compression

if you goto ford dealer they can usually look it up bring all numbers and registration and license
