Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Error Codes

Connect the OBD-II scanner and note any error codes. If codes related to the fuel system or throttle body are present, proceed accordingly.

3. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reinstall the air intake duct and ensure all connections are secure.

4. Fuel System Inspection

Check the fuel pressure using a fuel pressure gauge at the fuel rail. Refer to manufacturer specifications for normal operating pressure.
Replace the fuel filter if clogged or if pressure is outside of specifications.
If necessary, inspect the fuel pump for operational issues by testing voltage and ground signals.

5. Ignition System Check

Remove spark plugs using a socket set and inspect for wear or damage; replace if necessary.
Test ignition coils with a multimeter to ensure they are within specifications; replace any faulty coils.

6. Reconnect Battery and Reset Codes

Reconnect the negative battery terminal.
Clear any stored error codes using the OBD-II scanner and take the vehicle for a test drive.
