Answers :

P0300 is random engine misfiring. Could be several problems. My car had this and I replaced the plugs and plug wires. No change. Checked the three coil units. They seemed ok. I used a new on in each spot and nothing changed. Ended up being the ignition control module that sits under the coils. Relatively easy to change. Costs around $150 at the parts store. This may correct the other codes.
