Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth or brush to remove carbon buildup.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter (refer to the owner's manual for precise location).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter and replace it with a new one.
Reconnect fuel lines, ensuring they are secure.

4. Inspect and Replace Spark Plugs

Remove ignition coil covers (if applicable) and disconnect ignition coils.
Remove old spark plugs using a spark plug socket.
Check the gap and condition of new spark plugs and install them with the specified torque (usually 13-15 ft-lbs).
Reinstall ignition coils and covers.

5. Transmission Fluid Check and Change (if necessary)

Locate the transmission dipstick; remove it and check fluid level.
If the fluid is low, add the correct type of ATF as specified in the owner's manual.
If the fluid appears burnt or dirty, perform a transmission fluid change, following the manufacturer's specifications.
