Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the battery before starting work on electrical components.
Tools required: OBD-II scanner, socket set, fuel pressure gauge, cleaning supplies.

2. Addressing Error Codes

If error codes are present, document them for reference.
Clear codes using the OBD-II scanner and take the vehicle for a test drive to see if the code reappears.

3. Air Filter Replacement

Locate the air filter housing and remove the screws or clips securing it.
Remove the old air filter and inspect the housing for debris.
Install a new air filter that meets manufacturer specifications.
Reassemble the housing and ensure it is secured.

4. Fuel Pressure Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading against manufacturer specifications.
If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.

5. Throttle Body Cleaning

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reinstall the intake duct and ensure all connections are tight.

6. Ignition Component Replacement

Remove the engine cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the old spark plugs using a spark plug socket and torque wrench.
Install new spark plugs and ignition coils, tightening them to the manufacturer's specified torque.
