Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool if it has been running.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it fits snugly.
Reattach the air filter housing cover and secure it with the bolts.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter in the fuel line.
Relieve the fuel system pressure by removing the fuel pump fuse or relay and running the engine until it stalls.
Disconnect the fuel lines from the filter using a fuel line disconnect tool.
Replace with a new fuel filter, ensuring the flow direction is correct.
Reconnect the fuel lines and reinstall the fuel pump fuse or relay.

4. Inspect and Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Clean the throttle body using throttle body cleaner and a soft cloth or brush, ensuring the butterfly valve operates freely.
Reattach the intake duct securely.

5. Transmission Fluid Check and Change

Check the transmission fluid level using the dipstick while the engine is running and at operating temperature.
If low, add the correct type of transmission fluid as specified in the owner's manual.
If fluid is burnt or discolored, consider performing a transmission fluid change:
- Remove the transmission pan using a socket set.
- Replace the filter and gasket.
- Reinstall the pan and refill with new transmission fluid.
