Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Clean or Replace Air Filter

Locate the air filter housing and open it.
Remove the old air filter.
Inspect the filter; if dirty, clean it or replace it with a new one.
Reinstall the air filter and close the housing.

3. Throttle Body Cleaning

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Ensure the throttle plate moves freely and is not sticking.
Reassemble the intake duct securely.

4. Fuel Pressure Test

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position (do not start) to check for proper pressure readings.
If pressure is below specifications, replace the fuel pump or check the fuel filter for clogs.
Disconnect the gauge and restore the fuel system.

5. Inspect and Replace Ignition Components

Remove the ignition coil cover (if applicable).
Inspect the spark plugs for wear; replace if necessary.
Check ignition coils for proper operation; replace if defective.
Reassemble all components and reconnect the battery.
