Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Addressing Error Codes

Connect the OBD-II scanner and record any fault codes.
Clear the codes and take the vehicle for a short test drive to see if they return.
Safety Warning: Always disconnect the battery before working on electrical systems.

3. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reattach the air intake duct and ensure it is secured.
Tools Required: Throttle body cleaner, cloth.

4. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "on" position (without starting the engine) and check for proper fuel pressure (consult the service manual for specifications).
If pressure is low, inspect and replace the fuel pump or fuel filter as necessary.
Tools Required: Fuel pressure gauge.

5. Inspect and Replace Spark Plugs/Ignition Coils

Remove the engine cover if necessary to access the spark plugs.
Inspect the spark plugs for wear and replace if necessary.
Check the ignition coils for proper function; replace any defective coils.
Tools Required: Socket set, torque wrench.
