Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery terminal to ensure safety during repairs.
Ensure the vehicle is on a level surface and secured with wheel chocks.

2. Inspect and Replace Air Filter

Sub-steps:
- Open the hood and locate the air filter housing.
- Unclip or unscrew the air filter housing cover.
- Remove the old air filter and inspect for dirt and debris.
- Install a new air filter, ensuring it fits snugly.
- Reassemble the air filter housing and secure it properly.

3. Clean or Replace Fuel Injectors

Sub-steps:
- Remove the fuel rail from the engine by disconnecting the fuel line and unbolting it.
- Carefully extract fuel injectors from the rail.
- Clean the injectors using a fuel injector cleaner kit or replace them if damaged.
- Reinstall the cleaned or new injectors into the fuel rail.
- Reattach the fuel rail to the engine and reconnect the fuel line.

4. Check and Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate tires to the manufacturer-recommended pressure (found in the owner’s manual or on a sticker inside the driver’s door).
- Inspect tires for uneven wear or damage and replace if necessary.

5. Change Engine Oil

Sub-steps:
- Drain the old engine oil using an oil catch pan by removing the oil drain plug.
- Replace the oil filter with a new one.
- Reinstall the drain plug and tighten to the specified torque (refer to owner’s manual).
- Fill with the recommended engine oil type and quantity (consult the owner’s manual).
- Start the engine and check for leaks around the oil filter and drain plug.
