Solution

1. Preparation

1. Gather necessary tools and parts.
2. Ensure the vehicle is parked on a level surface and the engine is cool.
3. Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Clean Throttle Body

2. Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
3. Reinstall the air intake duct securely.

3. Replace Air Filter

1. Locate the air filter housing.
2. Open the housing and remove the old air filter.
3. Install a new, clean air filter; ensure it fits securely.
4. Close the housing and ensure it is properly latched.

4. Check and Adjust Fuel Pressure

1. Connect a fuel pressure gauge to the fuel rail.
2. Start the engine and monitor the fuel pressure reading.
3. If pressure is below specifications, check the fuel pump and replace if necessary.
4. Disconnect the gauge and ensure the fuel line is secure.

5. Inspect and Replace Spark Plugs

1. Remove the ignition coils to access the spark plugs.
2. Using a spark plug socket, carefully remove each spark plug.
