Default Fault codes 2005 grand marquis

Suddenly started running (sounding like) a motorcycle at idle. Used dongle to run fault codes which follow:

PO109 Powertrain Manifold absolute pressure/barometric pressure circuit intermittent

PO 316 Engine Misfire

PO355 Ignition Coil "E" Primary/Secondary Circuit

PO 622 Generator Field "F" Terminal Control Circuit

I had absolutely no idea what any of this meant so googled these faults and had absolutely no idea what any of that meant. You may have surmised that I am not a mechanic though, to my credit, I have learned in my 75 years to open the hood and spot the battery right off - on some cars, anyway.

Before I am compelled to just turn the car over to a mechanic and say, "Fix it, please." perhaps one of you fine fellows might offer some guidance.

Thanks, Barry
