03 Dakota 4.7 coil problems
I have an 03 dakota with the 4.7 it is throwing codes 352-354-356-358 which is for coils i have tested the coils and have power to them and they are producing spark fuel pressure is at 50psi but it feels like im only running on the left bank of cylinders it starts fine and idles good for about 3-5 seconds then starts acting up does anyone know what could be the problem

That's every cylinder on the RH bank. Disconnect the battery and double check all the connection including at the PCM. I doubt it is a coil issue. You could always swap one of the LH coil packs to the RH bank and see if the code follows. Double check all grounds as well. It could be a PCM issue.

Put a test light connected to POSITIVE on the control wire for the coils on that side. If they burn solid while running, you have coil drivers grounded 100%. That's a PCM replacement.
