Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Replace the Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing.
Take out the old air filter and clean the housing interior.
Install the new air filter and secure the housing back in place.

3. Fuel Pressure Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
If the pressure is too low, proceed to check the fuel pump and replace if faulty.

4. Clean or Replace Fuel Injectors

Remove the fuel injectors from the fuel rail.
Use a fuel injector cleaning kit or professional cleaning service to clean the injectors.
If they are damaged or leaking, replace with new injectors.

5. Tire Pressure Adjustment

Check the manufacturer's recommended tire pressure.
Inflate or deflate each tire as necessary to achieve the correct pressure.

6. Oil Change

Drain the old engine oil using a wrench to remove the oil drain plug.
Replace the oil filter using an oil filter wrench.
Refill with the manufacturer's recommended oil type and amount.
