So my 2010 avenger sxt 2.4l 4 cyl POS has a very rough idle no acceleration at all, etc and cel lights are on, just replaced the alternator and battery, both are in good working order, it's not the coil packs, I'm baffled at what it could be.. please help..

Try to check all ground connections under the hood. Also check all connections on the bottom of the TIPM for corrosion. Have you cleaned the throttle body anytime in the past? A good cleaning with SeaFoam spray might help. Some SeaFoam liquid in the tank regularly helps also. Don't know what maintenance has been performed on your car.

Did you pull the TIPM and check the connections on the bottom?
