Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is parked on a level surface.

2. Replace Air Filter

Sub-steps:
1. Open the hood and locate the air filter housing.
2. Unclip or unscrew the air filter housing cover.
3. Remove the old air filter and inspect the housing for debris.
4. Install the new air filter, ensuring it fits securely.
5. Reattach the housing cover and secure it back in place.

3. Clean Throttle Body

Sub-steps:
1. Remove the intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the throttle plate.
3. Open the throttle plate manually to clean behind it.
4. Reattach the intake duct and ensure all clamps are tightened.

4. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil or spark plug wires carefully.
2. Use a spark plug socket to unscrew and remove the old spark plugs.
3. Check the gap on new spark plugs and adjust as necessary.
4. Install the new spark plugs and torque them to manufacturer's specifications.
5. Reconnect the ignition coils or spark plug wires.

5. Replace Fuel Filter (if applicable)

Sub-steps:
1. Locate the fuel filter (refer to the service manual for location).
2. Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
3. Disconnect the fuel lines from the filter (use caution for fuel spills).
4. Install the new fuel filter, ensuring the flow direction matches the markings.
5. Reconnect the fuel lines and replace the fuel pump fuse.
