Solution

1. Preparation

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

2. Addressing Air Intake Issues

Remove the air filter assembly.
Inspect the air filter for dirt and replace if necessary.
Check the intake hose for cracks or loose connections and replace as needed.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "on" position (do not start the engine) and check the pressure reading.
If pressure is low, replace the fuel pump and/or fuel filter as required.

4. Exhaust System Examination

Inspect the exhaust system visually for any signs of damage or blockage.
If the catalytic converter is found to be clogged, it must be replaced.
Use a backpressure gauge to confirm if the exhaust is obstructed.

5. Ignition System Repair

Remove the spark plugs using a socket wrench.
Inspect each plug for wear or damage; replace if necessary.
Check ignition coils for proper function and replace as needed.

6. Final Checks

Reconnect the battery.
Clear any diagnostic trouble codes using the OBD-II scanner.
Start the engine and allow it to reach operating temperature before taking a test drive.
