Default Pontiac Grand am

Picked up a grand am 2.2 liter. Running rough at idle when sitting in traffic or when I use heat and ac. I have changed the plugs and ICM after experiencing misfires. Checked battery 12.5 car off 14.5 car running. With heat, radio and lights on it maintains 14.5 so I believe the alternator and battery to be fine.
Any thoughts or suggestions appreciated. Thanks
