Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Replace Spark Plugs

Remove the engine cover (if applicable) using a socket set.
Disconnect ignition coil connectors.
Unbolt the ignition coils using a socket wrench and remove them.
Remove the old spark plugs using a spark plug socket, inspect for condition, and clean the area.
Install new spark plugs to the manufacturer’s specified torque (typically around 13-20 lb-ft).
Reinstall ignition coils and reconnect the connectors.

3. Inspect and Repair Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
If leaks are found, replace the damaged hoses with new ones, ensuring a tight fit.
Use a smoke machine or carburetor cleaner to identify any hidden leaks.

4. Check Fuel Injectors

Remove the fuel rail by unscrewing the bolts.
Disconnect the fuel lines carefully.
Inspect each injector for clogs and replace them if necessary.
Reinstall the fuel rail and secure it, then reconnect the fuel lines.

5. Clear Error Codes

Reconnect the battery and use the OBD-II scanner to clear any stored error codes.
Start the engine to ensure the check engine light does not return.
