How do you fix a Chevy truck with code PO301?

Answer 1

Code P0301 indicates a misfire in cylinder 1 of your Chevy truck. To fix this issue, first, inspect and replace the spark plug and ignition coil for that cylinder, as these are common culprits. Additionally, check for any vacuum leaks, fuel delivery issues, or compression problems in that cylinder. If the problem persists after these steps, consider running a diagnostic to rule out more complex issues.
