Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety before working on electrical components.
Allow the engine to cool down if it has been running.

2. Replace Faulty Components

Sub-steps:
1. For issues related to ignition misfires:
  - Remove spark plug wires and unscrew the spark plugs using a socket wrench.
  - Inspect spark plugs for wear; replace if necessary with OEM spark plugs (torque to manufacturer specifications).
  - Reattach spark plug wires securely.
2. If diagnosed with a faulty oxygen sensor:
  - Locate the oxygen sensor in the exhaust system.
  - Disconnect the electrical connector and unscrew the sensor using an O2 sensor socket.
  - Install the new oxygen sensor and reconnect the electrical connector (torque to manufacturer specifications).

3. Clear Fault Codes

Use the OBD-II scanner to clear any stored trouble codes after repairs are complete.
Reconnect the negative battery terminal.

4. Final Assembly

Ensure all components and connectors are properly reattached.
Replace any engine covers or shields removed during the process.
