The engine dashboard light is on on my car. The engine vibrates and has a lack of power.
The diagnostic tool show the trouble code P0304.
It means that there are misfire on the cylinder number 4.
After having tested the charging circuit, I test the ignition coil on the defective cylinder with an ignition coil tester.
