Error Code: P0300
Description: Random/Multiple Cylinder(s) - Misfire Detected
Error Code: P0301
Description: Cylinder number 1 misfire detected.
Regarding both of the codes look into the following areas.
Possible Causes:
- Air Intake System leaking.
- Fuel Supply faulty.
- Injector(s) faulty.
- Ignition Cable(s) and/or Spark Plug(s) faulty.
- Ignition coil(s).Exhaust Gas Recirculation (EGR) Valve stuck/open.
- Camshaft Position Sensor faulty.
- Low compression.
- Wiring.

Could be any of the above. Sounds like you have eliminated spark plugs. You could theoretically test the ignition coils by removing one at a time while the car is running and see if it sputters, but I would only do so if you are wearing rubber mechanics gloves. If the car has enough miles to warrant replacing the spark plugs, you may just want to replace the ignition coils anyways.

Hi bro ignition4less, the spark plugs are mentioned in the line 4 of para 2 and I quote (- Ignition Cable(s) and/or SparkPlug(s) faulty). Spark plug is one of the main causes of misfire. The ignition coils are not always necessarily replaced with the spark plugs. Logically all the parts do not go bad at the same time.
Thanks.
