Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean any carbon deposits inside the throttle body.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter, usually near the fuel tank or engine bay.
Use a socket set to disconnect the fuel lines carefully (be cautious of fuel spillage).
Replace the old fuel filter with a new one, ensuring the flow direction is correct.
Reconnect the fuel lines and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable) using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs and inspect their condition.
Replace with new spark plugs, ensuring the gap is set to the manufacturer's specification.
Reinstall the ignition coils and covers securely.

5. Test Drive

Reconnect the battery and start the engine, allowing it to idle.
Conduct a test drive to check for improvements in acceleration and responsiveness.
