Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, flashlight
Safety Warning: Disconnect the battery before working on electrical systems.

2. Check Oil Level and Type

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If the oil is low, add the appropriate type of oil as specified in the owner’s manual.

3. Inspect and Replace Oil Filter

Locate the oil filter and check for proper installation.
If leaking, remove the oil filter using an oil filter wrench.
Apply a thin layer of new oil to the rubber O-ring of the new filter.
Install the new oil filter and tighten it to the manufacturer's specifications (usually hand-tight plus a quarter turn).

4. Check Air Intake System

Inspect the air intake hose for any disconnections, cracks, or damage.
Ensure the air filter is clean and properly seated. Replace if necessary.

5. Inspect Electrical Connections

Visually check all wiring harnesses and connectors around the engine, especially those related to the ignition system and fuel injectors.
Reconnect any loose connectors and ensure they are secure.

6. Test Drive and Monitor

Reconnect the battery and start the engine.
Allow the engine to idle and monitor for roughness or unusual noises.
Take the vehicle for a short test drive to confirm smooth operation.
