Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, torque wrench, screwdriver, safety glasses, gloves.
Disconnect the battery before starting the repair to prevent electrical issues.

2. Address Error Codes

If error codes are present, refer to the vehicle’s service manual to diagnose and address the specific issue indicated by the codes (e.g., replace faulty sensors).

3. Change Air Filter

Remove the air filter cover using a screwdriver.
Take out the old air filter and replace it with a new one, ensuring it fits snugly.
Reattach the air filter cover and tighten screws to manufacturer specifications.

4. Fuel System Inspection

Fuel Pressure Test:
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition to the "On" position (do not start) to check pressure readings.
- If pressure is low, replace the fuel pump or clean the fuel filter as necessary.

5. Clean Throttle Body

Remove the intake duct from the throttle body using the socket set.
Spray throttle body cleaner into the throttle body and wipe clean using a lint-free cloth.
Reinstall the intake duct and ensure all clamps are tightened properly.

6. Exhaust System Check

Visually inspect the exhaust system for any visible damage or rust.
If blockages are suspected, remove and inspect the catalytic converter for clogs.
Replace any damaged components and ensure proper sealing of exhaust joints.
