Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Attach a fuel pressure gauge to the fuel rail.
3. Turn the ignition key to the "On" position (do not start the engine) and check the fuel pressure reading against manufacturer specifications.
4. If pressure is low, inspect the fuel filter for clogs and replace if necessary.
5. If the filter is fine, check the fuel pump for proper operation and replace if faulty.

3. Ignition System Maintenance

Sub-steps:
1. Remove the spark plug wires and inspect for damage.
2. Remove the spark plugs using a socket set and inspect for wear (burnt tips or excessive carbon buildup).
3. Replace worn spark plugs with new ones, ensuring to gap them according to manufacturer specifications.
4. Reconnect the spark plug wires securely.

4. Throttle Body Cleaning

Sub-steps:
1. Disconnect the throttle body electrical connector and remove the inlet duct.
2. Use throttle body cleaner and a soft brush to clean the throttle body.
3. Ensure the throttle plate can open and close freely.
4. Reinstall the throttle body and reconnect the inlet duct.

5. Final Assembly and Testing

Sub-steps:
1. Reconnect the battery terminal and start the engine.
2. Allow the engine to reach operating temperature, then take the vehicle for a test drive.
3. Monitor performance during the drive to confirm that power loss has been resolved.
