P0350 Ignition Coil Primary/Secondary Circuit Malfunction

Is this just faulty coilpacks? Its not stating WHICH coilpack it is, just a generic code.

Should I be replacing all the coils?

The car has already been wired for a GD motor, and already had ONE GD motor in it. I never had this code come up on the old WRX motor, so the ignition wires leading to the motor aren't bad, possibly the sparkplug wires or wires ON the motor might be bad.

The CEL flashes intermittently. On/off/on/off.

From what I've seen the motor runs perfect.

So I'm kind of lost... could it be ECU related?

what ecu are you using? are you still using the jdm wrx or are you actually using a v7 ecu now? do you have a lightened flywheel? if the cel is flashing then its likely a misfire... or at least the ecu thinks your motor is misfiring. is this at idle? my old rex motor did the same thing, but my rex motor was usdm, and i know yours is jdm, although theres not a huge difference. i might be able to help you out.
