Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt.
If dirty, clean it with compressed air or replace it with a new one.
Reinstall the air filter and housing cover, ensuring it is secure.

3. Inspect and Clean Throttle Body

Remove the throttle body assembly by disconnecting the intake duct and electrical connectors.
Use throttle body cleaner and a soft cloth to clean inside the throttle body.
Ensure the throttle plate moves freely and is not obstructed.
Reinstall the throttle body and reconnect all hoses and electrical connectors.

4. Replace Spark Plugs

Remove the ignition coil by unbolting it and disconnecting the electrical connector.
Take out the spark plug using a spark plug socket and ratchet.
Inspect the old spark plug for wear; replace with new spark plugs if necessary.
Reinstall the ignition coil and reconnect the electrical connector.

5. Check Fuel System

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check fuel pressure.
If pressure is below specifications, consider replacing the fuel pump or filter.
After completion, disconnect the pressure gauge.

6. Inspect for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine to identify any hidden leaks.
Replace any damaged hoses and ensure all connections are tight.
