Engine running rough

During the winter up here my Patriot started to run real hard and sound like straight trash. I am at a loss as to what it could be. I changed the oil and filter the other week and have checked the other fluids and the belt. Nothing seems to be wrong. Any help will be appreciated. Even if it is directing me to another link. I ran the diagnostics on my code reader and in all honesty I can't tell if everything is in the normal limits. It sounds like something is rattling or maybe a bearing is going on one of the flywheels. Tried to upload a video but computers and I are not getting along.

It's a 2009 with auto trans?

Any MIL's or codes?

When's the last time the plugs were changed?

Loose heat shield? Worn engine mounts? Damaged exhaust system? Those are good places to start especially if no codes present.

These are only 30,000 miles spark plugs. Start with something obvious and cheap.
