Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, screwdriver set, and cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Clear Trouble Codes

Use the OBD-II scanner to read and clear any trouble codes.
Document any codes for future reference.

3. Inspect and Clean the Throttle Body

Disconnect the battery to avoid electrical issues.
Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reassemble the intake duct and reconnect the battery.

4. Replace the Air Filter

Locate the air filter housing and unclip the cover.
Remove the old air filter and inspect for dirt and damage.
Install a new, clean air filter and secure the housing cover.

5. Test and Replace Fuel Filter (if applicable)

Attach the fuel pressure gauge to the fuel rail test port.
Turn the ignition key to the ON position (do not start the engine) and check the pressure reading against specifications.
If pressure is low, locate and replace the fuel filter according to manufacturer guidelines.

6. Inspect and Clean Fuel Injectors

Remove the fuel rail to access the injectors.
Use a fuel injector cleaner or have them professionally cleaned if they are clogged.
Reinstall the injectors and fuel rail, ensuring all connections are secure.
