Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Replace Air Filter

Tools Required: Screwdriver or ratchet set, replacement air filter.
Steps:
1. Open the hood and locate the air filter box.
2. Unclip or unscrew the housing cover to access the air filter.
3. Remove the old air filter and clean the housing if necessary.
4. Install the new air filter, ensuring it fits securely in place.
5. Reattach the housing cover and ensure it is sealed properly.

3. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, replacement spark plugs.
Steps:
1. Disconnect the negative battery terminal to prevent electrical shock.
2. Remove the ignition coil by unscrewing it from the cylinder head.
3. Carefully pull the spark plug out using a spark plug socket.
4. Inspect the old spark plug for wear; replace if necessary.
5. Install the new spark plug to the manufacturer's specified torque (typically 13-15 ft-lbs).
6. Reinstall the ignition coil and reconnect the battery terminal.

4. Clean the Throttle Body

Tools Required: Throttle body cleaner, rag or brush, socket set.
Steps:
1. Disconnect the negative battery terminal.
2. Remove the intake duct connected to the throttle body.
3. Spray throttle body cleaner onto a rag or directly into the throttle body.
4. Use a brush or rag to scrub away any carbon deposits.
5. Ensure the throttle plate moves freely and reinstall the intake duct.

5. Check and Replace Fuel Filter (if applicable)

Tools Required: Fuel line disconnect tool, replacement fuel filter.
Steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Disconnect the fuel lines from the fuel filter using a fuel line disconnect tool.
3. Remove the old fuel filter and install the new one, ensuring correct flow direction.
4. Reconnect the fuel lines and reinstall the fuel pump fuse.
