So I've been noticing the last couple months that I have rough idle with AC on and in gear. And today the drive just feels different. I noticed on a 70mile commute home that at points it felt rough even in cruise like the car would have little jerks. (Not left or right jerks). And got home, shut the voy off and noticed a shake and a rattle sound. With the hood open, I turned it on and shut it off a few more times, and noticed the engine shake a decent amount side to side when shut off. I'm thinking motor mounts, but would like some opinions/input. Thanks
motor mounts?

Have you visually inspected the engine mounts to see if they look broken? sometimes you have to get a jack under the engine and lift it up slightly to see if they are ripped.

on an I6, the passenger side tends to go first because of the exhaust heat. This coupled with the fact that the passenger side is easier to get to, you may want to just swap that side out and see if it feels better.
Agreed. And only use Delco OEM mounts. Aftermarket ones are too stiff, and have been reported to not solve the idle vibration.

My tranny mount was DEAD and my motor mounts are still A-OK. You can see it by looking under and having someone shift reverse to drive with the brakes held on.

Ok it is extremely rare if you don't have a jacked up 4x4 and go off roading? In 15 years I've only seen one transmission mount that was bad on a rear wheels drive vehicle.
