Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt or damage.
If dirty, clean it if reusable; otherwise, replace it with a new air filter.
Reinstall the air filter and housing cover securely.

3. Throttle Body Cleaning

Locate the throttle body and remove the intake duct.
Use a throttle body cleaner and a soft brush to clean the throttle plate and interior.
Reassemble the intake duct and ensure all clamps are tight.

4. Transmission Fluid Check and Replacement (if needed)

Locate the transmission dipstick and check the fluid level; add fluid if low.
If the fluid is dirty or has a burnt smell, perform a fluid change:
- Drain the transmission fluid through the drain plug.
- Replace the filter and gaskets if applicable.
- Refill with manufacturer-recommended transmission fluid.

5. Fuel System Inspection

Inspect the fuel pump by listening for its operation when the ignition is turned on.
If needed, replace the fuel pump or filter based on inspection results.
