Solution

1. Preparation

Gather tools and ensure a clean workspace.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Faulty Components

Sub-step 1: If error codes indicate a faulty spark plug or ignition coil:
- Remove the engine cover if applicable.
- Disconnect electrical connectors and remove the faulty spark plug or coil using a socket set.
- Replace with new components, ensuring they are torqued to manufacturer specifications (typically around 12-15 Nm for spark plugs).
Sub-step 2: If a vacuum leak is found:
- Identify the damaged hose visually or with a smoke test.
- Remove the damaged section and replace with new vacuum hose of the same diameter.

3. Reset Engine Light

After repairs, reconnect the battery terminal.
Use the OBD-II scanner to clear any stored error codes, ensuring the check engine light is reset.

4. Test Drive

Conduct a test drive to monitor for any return of symptoms or illumination of the engine light.
