Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body and scrub with a soft brush to remove carbon buildup.
Wipe clean with a lint-free cloth.
Reinstall the air intake duct and tighten the clamps securely.

3. Check and Replace Fuel Filter

Locate the fuel filter; typically found along the fuel line under the car.
Use a wrench to disconnect the fuel lines from the filter (be cautious of fuel spillage).
Remove the old fuel filter and replace it with a new one, ensuring the flow direction is correct.
Reconnect the fuel lines securely.

4. Inspect and Replace Spark Plugs

Remove the ignition coils or spark plug wires from the spark plugs using a socket set.
Remove the spark plugs with a spark plug socket and inspect for wear or deposits.
Replace with new spark plugs according to manufacturer specifications (check gap settings).
Reinstall the ignition coils or spark plug wires.

5. Test Drive

Reconnect the battery.
Start the engine and let it idle for a few minutes.
Perform a test drive to check for hesitation during acceleration.
