Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the engine to cool down before starting work.

2. Clean or Replace Air Filter

Remove the air filter cover using a screwdriver or socket set.
Inspect the air filter for dirt and debris; replace it if necessary with a new OEM filter.
Reattach the air filter cover securely.

3. Inspect and Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reassemble the intake duct, ensuring all clamps are tight.

4. Check and Replace Spark Plugs

Remove the ignition coils using a socket set. Label each coil for correct placement.
Extract the spark plugs using a spark plug socket and inspect for wear or carbon buildup.
Replace any worn spark plugs with new OEM plugs, tightening to the manufacturer's torque specifications (typically around 13-15 lb-ft).
Reinstall the ignition coils.

5. Test and Replace Fuel Pressure Regulator (if needed)

Attach a fuel pressure gauge to the fuel rail and start the engine.
Check the fuel pressure; it should be within the specified range (usually 50-60 psi for many models).
If pressure is low, replace the fuel pressure regulator following the manufacturer’s instructions.
