Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace the Air Filter

Remove the air intake duct by loosening the clamps with a socket set.
Take out the old air filter and inspect it.
Install a new OEM or high-quality air filter, ensuring it fits snugly.
Reattach the air intake duct and secure it.

3. Clean or Replace Fuel Injectors

If cleaning, use a fuel injector cleaning kit or professional service.
If replacing, disconnect the fuel lines carefully and remove the fuel rail.
Replace the injectors with new ones, ensuring O-rings are properly lubricated.
Reconnect the fuel rail and lines, ensuring there are no leaks.

4. Check and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in all tires.
Inflate tires to the manufacturer's recommended pressure found in the owner’s manual or on the door jamb.
Inspect the tires for uneven wear, which may indicate alignment issues.

5. Change Engine Oil

Drain old engine oil using a wrench and oil drain pan; replace with new oil as per manufacturer specifications.
Replace the oil filter with a new one, ensuring proper installation.
Refill with the correct type and amount of oil, checking levels with the dipstick.
