Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is parked on a level surface and the engine is cold.
Disconnect the negative terminal of the battery for safety.

2. Replace Air Filter

Tools Required: Screwdriver or pliers (if applicable).
Remove the air filter housing cover.
Take out the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it fits securely, and replace the housing cover.

3. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaning kit or replacement injectors.
Disconnect the fuel lines and electrical connectors from the injectors.
Remove the fuel rail and injectors from the engine.
Clean the injectors using a cleaning kit, or replace them with new units if necessary.
Reassemble the fuel rail and reconnect the fuel lines and electrical connectors.

4. Check and Adjust Tire Pressure

Tools Required: Tire pressure gauge and air compressor.
Use the tire pressure gauge to check the pressure in all four tires.
Inflate or deflate each tire to the manufacturer's recommended pressure, which can be found on the driver's side door jamb.

5. Change Engine Oil

Tools Required: Wrench set, oil filter wrench, oil catch pan.
Drain the old engine oil by removing the drain plug and allow it to fully drain into the catch pan.
Replace the oil filter with a new one, using the oil filter wrench.
Reinstall the drain plug and fill the engine with the correct type and amount of new engine oil.
