Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set, and tire pressure gauge.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery before working on electrical components.

2. Replace Air Filter

Locate the air filter housing and remove the clips or screws.
Carefully pull out the old air filter and inspect for dirt and damage.
Insert a new, clean air filter, ensuring it fits snugly in the housing.
Reassemble the housing and secure it with clips or screws.

3. Fuel System Inspection

Fuel Pressure Check:
- Connect the fuel pressure gauge to the fuel rail test port.
- Turn the ignition to the "ON" position (without starting the engine) to check the pressure reading.
- Compare the reading to the manufacturer's specifications; replace the fuel pump if it is below specifications.
Fuel Injector Cleaning:
- Remove the fuel injectors from the fuel rail.
- Use a professional fuel injector cleaning kit to clean the injectors.
- Reinstall the injectors and fuel rail, ensuring all connections are tight.

4. Tire Pressure Adjustment

Use the tire pressure gauge to check the tire pressure on all four tires.
Inflate tires to the manufacturer-recommended pressure found on the driver’s door jamb.
Inspect tires for uneven wear and consider rotation or replacement as needed.

5. Coolant Temperature Check

Remove the engine cover if applicable.
Connect a multimeter to the coolant temperature sensor to verify its resistance against specifications.
If the sensor is faulty, replace it to ensure accurate temperature readings.
