Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools: OBD-II scanner, socket set, torque wrench, multimeter.

2. Diagnose Fault Codes

Reconnect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any fault codes that are present.
Cross-reference the codes to identify potential issues.

3. Inspect Ignition Components

Remove the engine cover if necessary for access.
Disconnect the ignition coils and inspect for damage or corrosion.
Remove spark plugs using a socket set; inspect for wear or fouling.
Replace any faulty ignition coils or spark plugs as needed (use OEM parts).

4. Check Fuel Injectors

Disconnect the fuel injector connectors.
Use a multimeter to test the resistance of each injector (specifications vary by model).
Replace any injectors that do not meet specifications.

5. Inspect Air Intake System

Visually check the air filter for dirt and debris; replace if clogged.
Inspect the intake hoses for cracks or loose connections.
Clean the throttle body if necessary, using throttle body cleaner.

6. Address Vacuum Leaks

Use a smoke machine to test for vacuum leaks in the intake manifold.
Replace any damaged hoses or gaskets found during the inspection.
