Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Address Error Codes

Use the OBD-II scanner to read and document any stored trouble codes.
Research codes to identify specific components needing attention.

3. Inspect Air Intake System

Remove the air filter and inspect for dirt and debris.
Clean or replace the air filter if necessary.
Check the intake ducts for cracks or loose connections and secure them.

4. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition key to the "On" position without starting the engine; check the reading.
If the pressure is below specifications, inspect the fuel pump and filter for issues.

5. Examine Ignition System

Remove the spark plugs for inspection; check for wear or carbon buildup.
Replace worn spark plugs with OEM specifications.
Test ignition coils with a multimeter to ensure they operate within the manufacturer’s specifications.

6. Inspect Exhaust System

Visually check for any visible blockages or damage in the exhaust pipes and catalytic converter.
Replace any damaged components as needed.

7. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the engine and conduct a test drive to ensure that power loss issues are resolved.
