Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting work.

2. Clean the Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft brush to clean the internal surfaces thoroughly.
Reinstall the throttle body, ensuring all gaskets are intact and properly seated.

3. Check and Replace Fuel Filter

Locate the fuel filter; refer to the vehicle manual for specific location.
Disconnect the fuel lines using a line removal tool.
Remove the old fuel filter and install a new one, ensuring correct orientation.
Reconnect the fuel lines securely.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable) to access the spark plugs.
Use a spark plug socket to remove old spark plugs.
Check the gap on new spark plugs and install them with the manufacturer-recommended torque specification.
Reinstall the ignition coil cover.

5. Transmission Fluid Check and Change

Locate the transmission dipstick; check fluid level and condition.
If low or contaminated, drain the old fluid and replace it with the manufacturer-recommended transmission fluid.
Use a funnel to refill the transmission fluid to the proper level.
