Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, socket set, multimeter, and replacement air filter.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to avoid any electrical issues while working.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the recommended PSI indicated on the driver’s side door jamb.
Recheck the pressure after inflating and ensure it is consistent across all tires.

3. Air Filter Replacement

Locate the air filter housing and remove the screws or clips holding it in place.
Carefully lift the air filter out and inspect for dirt or blockages.
Replace with a new air filter, ensuring it fits snugly into the housing.
Re-secure the housing with screws or clips.

4. Fuel System Inspection

Inspect fuel lines and connections for any signs of leaks or damage.
Remove the fuel filter based on the manufacturer's instructions and replace it if clogged.
Use a fuel injector cleaner to clean the injectors, or remove them for professional cleaning if necessary.

5. MAF Sensor Testing

Locate the MAF sensor, typically found between the air filter and throttle body.
Disconnect the electrical connector and remove the sensor.
Use a multimeter to check the sensor readings against specifications (refer to vehicle service manual).
Clean the sensor with MAF cleaner and reinstall it.

6. Engine Oil Change (if overdue)

Drain the old engine oil using a socket set to remove the oil drain plug.
Replace the oil filter with a new one.
Refill the engine with the manufacturer-recommended oil type and quantity.
