Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, engine oil, spark plug socket.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and drain the old oil into a pan.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque it to the manufacturer's specification (usually around 20-30 lb-ft).
4. Fill the engine with new oil, ensuring it meets the specifications (e.g., 0W-20).
5. Start the engine and check for leaks.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils using a socket wrench.
2. Remove the old spark plugs using a spark plug socket.
3. Check the gap on the new spark plugs and adjust if necessary (usually around 0.044 inches).
4. Install the new spark plugs and torque them to the specified value (typically around 13-15 lb-ft).
5. Reinstall the ignition coils.

4. Fuel System Inspection

Sub-steps:
1. Check for any fuel contamination; drain and replace with high-quality fuel if necessary.
2. Use a fuel pressure gauge to check the fuel system pressure and ensure it meets specifications.
3. If the fuel pump is faulty, replace it according to the manufacturer's guidelines.
