Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before working on it.

2. Replace Air Filter

Locate the air filter housing and open it.
Remove the old air filter and inspect it for dirt or damage.
Install a new air filter, ensuring it is seated properly in the housing.
Reassemble the air filter housing.

3. 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.
Ensure the throttle plate operates smoothly.
Reattach the air intake duct.

4. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Start the engine and check the reading to ensure it meets manufacturer specifications.
If the fuel pressure is low, replace the fuel pump following these sub-steps:
- Relieve fuel pressure by removing the fuel pump relay.
- Disconnect the battery and drain the fuel tank as needed.
- Remove the fuel pump access cover and disconnect the fuel lines.
- Remove the old fuel pump and replace it with the new one.
- Reconnect the fuel lines and reassemble everything.

5. Check and Replace Spark Plugs

Remove the ignition coil covers to access the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plugs for wear and replace them with new ones if necessary.
Reinstall the ignition coils and covers.
