Solution

1. Preparation

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

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and body.
Reattach the air intake duct securely.

3. Replace Throttle Position Sensor (if faulty)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Install the new throttle position sensor and reconnect the connector.

4. Check and Replace Fuel Filter (if clogged)

Identify the location of the fuel filter (may vary by model).
Relieve the fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using the appropriate tool.
Replace the old filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and fuse.

5. Fluid Change and Inspection

Check the transmission fluid level using the dipstick.
If low or dirty, drain the transmission fluid using a fluid extractor.
Replace with the manufacturer-recommended transmission fluid.
Inspect for leaks and ensure all connections are secure.
