Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is cool.
Tools required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies.
Safety warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before working on components.

2. Air Intake Inspection

Remove the air intake duct and inspect the air filter.
- If dirty, replace it with a new one.
Check for any blockages in the intake manifold or throttle body.
- Clean the throttle body using throttle body cleaner, ensuring to remove any carbon buildup.

3. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) to check fuel pressure readings.
- If pressure is below specifications (consult service manual for values), replace the fuel pump or fuel filter as needed.

4. Ignition System Inspection

Remove the spark plugs using a socket wrench and inspect their condition.
- Replace any worn or fouled spark plugs with the correct OEM specification plugs.
Test ignition coils with a multimeter to ensure they are within the specified resistance range.
- Replace any faulty ignition coils.

5. Final Assembly

Reassemble all components carefully, ensuring all connections are secure.
Reconnect the battery and clear any trouble codes using the OBD-II scanner.
