Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Replace Air Filter

Locate the air filter housing and release any clips or screws.
Remove the old air filter carefully.
Install the new air filter, ensuring it fits securely in place.
Reattach the housing and tighten any clips or screws.

3. Clean or Replace Fuel Injectors

Remove the engine cover if applicable (use a socket set).
Disconnect the fuel rail and remove the fuel injectors.
Clean the injectors using a specialized cleaner or replace them if excessively dirty or damaged.
Reinstall the injectors and reconnect the fuel rail securely.

4. Check and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate the tires to the manufacturer's recommended pressure found on the door jamb or owner’s manual.
Inspect the tires for any signs of uneven wear or damage.

5. Change Engine Oil

Drain the old oil using an oil drain pan.
Replace the oil filter (using an oil filter wrench).
Refill the engine with new oil, ensuring to use the correct type and viscosity as specified in the owner’s manual.
Run the engine for a few minutes and check the oil level, topping off if necessary.
