Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Reattach the intake duct securely.

3. Replace the Air Filter

Open the air filter box and remove the old air filter.
Install a new air filter, ensuring it fits snugly in the box.
Close the air filter box.

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires (depending on the engine type).
Use a spark plug socket to remove the old spark plugs.
Inspect for wear; replace with new plugs if necessary, ensuring they are gapped to manufacturer specifications.
Reinstall the ignition coil or spark plug wires.

5. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and remove the old filter.
Install a new fuel filter in the correct orientation and reconnect the fuel lines.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle, checking for any unusual noises or vibrations.
