P0300 Mitsubishi -

Question

I have a PO300 code. I had recently replaced plugs & wires. Check engine light came back on. I'm guessing since the ignition coils weren't replaced when the plugs & wire were, that this is the issue. It has lack of power at times, with engine hesitation. Would you agree?
