Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool down before commencing work.

2. Inspect and Clean Throttle Body

Remove the air intake duct leading to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle body, ensuring all carbon deposits are removed.
Reattach the air intake duct securely.

3. Replace Spark Plugs and Ignition Coils (if needed)

Remove the engine cover (if applicable) to access spark plugs.
Use a socket wrench to remove the old spark plugs; check for wear or damage.
Install new spark plugs to the manufacturer's specified torque (typically 15-20 Nm).
If ignition coils are faulty, remove them and replace with new ones, ensuring proper fit.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter (usually along the fuel line).
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter and replace it with a new one, ensuring proper orientation.
Reconnect fuel lines and check for leaks before starting the engine.

5. Final Reassembly

Reconnect the battery.
Start the engine and allow it to idle for a few minutes, checking for any irregularities.
