Solution

1. Preparation

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

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the air filter cover.
Take out the old air filter and replace it with a new one.
Reassemble the housing and secure it properly.

3. Check Fuel System

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition key to the "On" position (do not start the engine) to measure the fuel pressure.
If the pressure is below specifications, replace the fuel pump or clogged fuel filter as necessary.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

5. Inspect and Replace Ignition Components

Remove the ignition coils and spark plugs.
Inspect spark plugs for wear or damage; replace them if necessary.
Test each ignition coil with a multimeter for proper resistance; replace any faulty coils.
