Default 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

Default How to post

I am finding it amazingly difficult to understand how to start new thread. My fault, I'm sure. But, nothing jumps out at me (except for the once by accident) that says, "Start new thread." I believe that, for help, I should be posting in General tech help - or someplace else - but cannot figure out how to get there and start a new thread. Perhaps you can help. I'm sure you could - if only you would.
