Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace Air Filter (if necessary)

Remove the air filter cover using a screwdriver.
Take out the old air filter and inspect it.
Install a new air filter ensuring it fits snugly.
Reattach the air filter cover securely.

3. Fuel Pressure Testing

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position without starting the engine to check the pressure reading.
If pressure is below specification (consult manufacturer specifications), replace the fuel pump.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold by loosening the clamps and bolts.
Use throttle body cleaner and a soft brush to clean the inside surfaces.
Reinstall the throttle body and ensure all connections are tight.

5. Spark Plug and Ignition Coil Replacement

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coil connectors and remove the coils.
Unscrew the spark plugs using a spark plug socket and inspect for wear.
Replace with new spark plugs, ensuring proper gap settings.
Reinstall the ignition coils and reconnect the connectors.
