Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to ensure safety during repairs.

2. Addressing Engine Codes

Sub-steps:
1. Use the OBD-II scanner to read any trouble codes.
2. Document the codes and research them for specific issues related to the loss of power.
3. Clear the codes and take the vehicle for a test drive to see if they return.

3. Cleaning or Replacing the Air Filter

Tools Required: Screwdriver, replacement air filter
Sub-steps:
1. Remove the air intake cover using a screwdriver.
2. Take out the old air filter and inspect it for dirt and debris.
3. If dirty, clean it with compressed air or replace it with a new filter.
4. Reinstall the air intake cover securely.

4. Inspecting and Cleaning the Throttle Body

Tools Required: Throttle body cleaner, soft cloth
Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Spray throttle body cleaner inside the throttle body and clean it with a soft cloth.
3. Reassemble the air intake duct after cleaning.

5. Checking and Replacing Spark Plugs

Tools Required: Socket set, spark plug socket, torque wrench, replacement spark plugs
Sub-steps:
1. Remove the ignition coil cover and disconnect the ignition coils.
2. Use the spark plug socket to remove the old spark plugs.
3. Inspect the old plugs for wear; replace if necessary.
4. Install new spark plugs with the specified torque (typically 13-16 lb-ft).
5. Reconnect the ignition coils and cover.
