Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect for dirt or damage.
Clean the filter with compressed air or replace it if necessary.
Reinstall the air filter and housing cover securely.

3. Check and Adjust Fuel Pressure

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition key to the "ON" position without starting the engine.
Note the pressure reading; it should be within manufacturer specifications (typically 30-45 psi).
If pressure is low, check the fuel pump and replace if necessary.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the throttle plate and interior surfaces.
Ensure the throttle plate moves freely; if it sticks, replace the throttle body.
Reinstall the intake duct securely.

5. Inspect and Replace Ignition Components

Remove the ignition coil cover using a socket set.
Pull out the ignition coils and inspect for cracks or wear.
Replace worn spark plugs and coils with OEM parts as needed.
Reinstall the ignition coils and cover securely.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any trouble codes.
Start the engine and check for improvement in performance.
