Solution

1. Preparation

Gather all tools and parts needed for the maintenance tasks.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Tire Maintenance

Tools Required: Tire pressure gauge, air compressor.
Check each tire’s pressure using the gauge and inflate to the recommended PSI found on the driver’s side door jamb.
Inspect tires for uneven wear and replace if necessary.

3. Replace Air Filter

Tools Required: Screwdriver or socket set (depending on air filter housing).
Open the air filter housing by removing the screws or clips.
Take out the old air filter and clean any debris in the housing.
Install a new, clean air filter, ensuring it fits snugly.

4. Spark Plug Maintenance

Tools Required: Socket set, torque wrench.
Remove the ignition coil (if applicable) to access the spark plugs.
Unscrew the old spark plugs using a socket and replace them with new ones, ensuring they are gapped correctly.
Tighten the new spark plugs to the manufacturer’s specified torque.

5. Fuel System Inspection

Tools Required: Fuel pressure gauge, cleaning solution for injectors.
Inspect fuel lines for leaks; replace any damaged lines.
Use a fuel injector cleaning solution to clean the injectors, or remove and clean them using an ultrasonic cleaner if necessary.

6. Engine Oil Change

Tools Required: Oil filter wrench, socket set, oil drain pan.
Drain the old engine oil and replace it with the manufacturer-recommended oil.
Replace the oil filter with a new one and ensure it is tightened correctly.
