Default Possible ecm issue with 06 300

Okay so I think I know what the problem with the car . I've been getting codes P0300 and P0301 , I switched the ing coil with 1&2 so if the coil is going bad it would throw the P0302 but I still throws the P0301 so the only other thing I can think of is the ECM . Does anyone know how to test one and if I buy a used ecm what steps do I have to do to get the car started ... any ideas would help

how about the rest of the basics first like spark or wire issue to coil or fuel injector?

Rule number one with car repair: If there's any doubt about what is wrong, always fix the cheapest thing(s) first.

I see there has been a lot of issues with P0300 and misfires. I have a 2006 3.5L keep getting a P0300. I can't seem to point out any specific cyl. Vehicle misses real bad in gear but ok in park and neutral. New plugs, intake runners are new. Doesn't miss all the time. Runs great once moving. At a stop it shakes and sometimes stalls. Sometimes it will shake then smooth out and darts off. I know there is a TSB for carbon but it doesn't seem to apply to my engine code. Stumped!!
