Solution

1. Preparation

Gather required tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean Throttle Body

Remove the air intake duct leading to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body, ensuring the butterfly valve moves freely.
Reattach the air intake duct securely.

3. Replace Fuel Filter (if applicable)

Locate the fuel filter and relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line wrench.
Replace the old filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Inspect and Replace Spark Plugs (if necessary)

Remove the ignition coils by unscrewing them from the cylinder head.
Extract the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and adjust as necessary.
Install the new spark plugs and reattach the ignition coils.

5. Verify Transmission Fluid Level

With the engine running and in park, check the transmission fluid level using the dipstick.
If low, add the manufacturer-recommended fluid type to the appropriate level.
