Solution

1. Preparation

Gather tools and materials: OBD-II scanner, tire pressure gauge, replacement air filter, engine oil (if necessary), and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Pressure Check and Adjustment

Use a tire pressure gauge to measure the tire pressure for all four tires.
Inflate tires to the recommended PSI specified in the owner’s manual or on the driver’s door jamb.
Inspect tires for wear and replace if necessary.

3. Air Filter Replacement

Locate the air filter housing and remove any screws or clips.
Carefully take out the old air filter and inspect for dirt and debris.
Replace it with a new air filter, ensuring it is seated properly in the housing.

4. Fuel System Inspection

Inspect the fuel injectors for clogs or leaks; clean or replace as necessary.
Check the fuel filter for blockages and replace if it has not been done in the last 30,000 miles.

5. Engine Oil Change

If the engine oil is dirty or not up to level, drain the old oil using an oil pan.
Replace with the manufacturer-recommended oil type and viscosity.
Change the oil filter as part of the oil change procedure.

6. Driving Habit Adjustments

Encourage smooth acceleration and braking to reduce fuel consumption.
Limit idling times and utilize cruise control on highways when possible.
