If a misfire is present and you suspect a fuel control condition, force the fuel system into Open Loop using the scan tool and allow the engine to run for a few minutes.

On the other hand, multiple misfire codes can indicate an issue, such as a vacuum leak or low fuel pressure, that affects various cylinders.

P0302 should be fixed as soon as possible. You’ll have to look at all possible causes to diagnose the problem properly. Have a professional mechanic check your vehicle if you don’t have the required DIY auto repair experience and skills.
