Misfire P0351,P0352,P0353,P0354,P0355, P0356 Meaning secondary circuit A,B,C,D,E,F . You may need a PCM If your car has a NGC controller it may have melted the ignition coil mounted on the spark plug. For these to happen You have a defective coil driver circuit in the PCM . This is a multiple coil failure, Before we go there lets do the basic are the connector connected? How about the conection at the juction area all connected, then pcm failed. These are secondary what is the secondary the signal that allows the coil to collapse the magnetic field and gives spark.

You need to clear the codes from the ECM, and re-run diagnostic code. If you still have codes
Check your grounds. If you still have power issues, re-check your wiring or firing order. If you have spark only on 2-4-6, where is your 1 - 3 - 5. If I remember correctly those vehicles have double ignition modules. One for the right bank and one for the left bank. But not sure. When was the last time you change your spark plug wires? Your PCV? Fuel Filter? Air Filter?. As for your cam shaft sensor, run a coninuity test on the harness and ensure is working correcty. Why did you change the ECM, those things hardly go bad, unless you disconnected it while you had power going to it. Probably nothing wrong with the old one.
Ensure you don't have vacuum leaks (PCV Valve, EGR Valve) Check your fuel pressure if you can. Suggest you change fuel filter. Could be partially clogged and not allowing the proper atomization of fuel. (Also did you gap your plugs correctly or just threw them on as is?)
