New Member with technical question

I have a 2009 G6 2.4L with 4spd automatic. It has 158K miles. About a year ago it started to get an occasional shake at an idle. Idle fine then a shake would occur. Then 3 minutes later another shake or buck. The check engine light comes on always with a P0303 code meaning cylinder 3 misfire. I changed all the ignition coils with AC delco coils, changed all the injectors with GM injectors and changed the exhaust manifold with converter (GM). I also changed the intake and exhaust camshaft actuators. Also at a long light idling the "Service Traction" display will come on. The car runs very strong, gets about 24mpg. I love the car except the problem at an idle. At a long light I usually put the tranny in neutral which calms down the occational shake. 25-50 rpm above an idle no problems.

From my research this is a common problem with the 2.2L and 2.4L engines in G6 and Malabu. Does anyone know a fix for this?
