Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery before working on electrical components.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter, inspecting it for dirt or damage.
Insert a new air filter, ensuring it is seated properly.
Reassemble the housing and secure it with screws or clips.

3. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaning kit or new fuel injectors.
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the injectors and remove any mounting bolts.
If cleaning, follow the injector cleaning kit instructions; if replacing, install new injectors and secure them.
Reconnect the fuel lines and check for leaks.

4. Check and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate tires to the recommended pressure specified in the owner's manual.
Inspect for uneven wear or damage and replace tires if necessary.

5. Inspect and Change Engine Oil

Check the engine oil level using the dipstick.
If low or dirty, drain the old oil using a socket set.
Replace with the manufacturer-recommended oil and a new oil filter.
Refill the engine with the appropriate amount of new oil.
