Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Attach a fuel pressure gauge to the port.
3. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading against specifications (typically 3-4 bar for Renault).
4. If pressure is low, check the fuel pump relay and fuse.
5. If necessary, replace the fuel filter and inspect the fuel pump for proper operation.

3. Spark Plug and Ignition Coil Replacement

Sub-steps:
1. Remove the engine cover if equipped.
2. Disconnect the ignition coil connectors.
3. Remove the ignition coils using a socket set.
4. Extract the spark plugs using a spark plug socket.
5. Inspect the spark plugs for wear; replace if necessary.
6. Install new spark plugs and reattach the ignition coils, ensuring they are seated properly.

4. Throttle Body Cleaning

Sub-steps:
1. Locate the throttle body, typically found between the air intake and the intake manifold.
2. Disconnect the throttle body connector and vacuum lines.
3. Remove the throttle body using a socket set.
4. Clean the throttle body with throttle body cleaner and a soft cloth to remove carbon buildup.
5. Reinstall the throttle body, reconnect all components, and ensure proper sealing.
