Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter (ensure it meets OEM specifications).
Reattach the housing cover and tighten to the manufacturer’s torque specifications.

3. Inspect and Replace Fuel Injectors (if necessary)

Locate the fuel rail and release the fuel pressure using a fuel pressure gauge.
Disconnect the electrical connectors and fuel lines from the injectors.
Remove the fuel injectors from the fuel rail using a socket set.
Install new fuel injectors, ensuring proper alignment and sealing.
Reconnect fuel lines and electrical connectors, then reapply fuel pressure.

4. Change Engine Oil and Filter

Raise the vehicle and secure it with jack stands.
Drain the old engine oil using an oil drain pan.
Replace the oil filter using an oil filter wrench.
Refill the engine with new oil (specify the type and viscosity based on manufacturer recommendations).

5. Verify Tire Pressure

Use a tire pressure gauge to check each tire’s pressure.
Inflate any under-inflated tires to the recommended PSI as indicated on the driver’s door jamb.
