Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body. Ensure no debris falls into the intake manifold.
Reattach the air intake duct securely.

3. Replace the Air Filter

Open the air filter housing and remove the old air filter.
Inspect the housing for debris and clean if necessary.
Install a new air filter, ensuring it fits snugly and seals properly.

4. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter (if serviceable) and remove it using the appropriate socket set.
Install a new fuel filter, ensuring the flow direction is correct as indicated by arrows on the filter.

5. Check and Replace Spark Plugs (if necessary)

Remove ignition coil covers and disconnect the coils.
Remove old spark plugs using a spark plug socket, inspecting for wear or damage.
Install new spark plugs to the manufacturer-specified torque (typically 12-15 ft-lbs).
