Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, engine oil, oil filter wrench, flashlight.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening the hood.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using jack stands and ensure it is secure.
2. Remove the drain plug from the oil pan and allow the old oil to completely drain into a suitable container.
3. Replace the oil filter using an oil filter wrench, ensuring the rubber gasket comes off with the old filter.
4. Install a new oil filter and tighten it according to manufacturer specifications.
5. Reinstall the drain plug and tighten to the proper torque specification (usually around 20-25 ft-lbs).
6. Fill the engine with new oil, checking the owner's manual for the correct oil type and capacity.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil cover if applicable, and disconnect the electrical connectors.
2. Remove the ignition coils using a socket set.
3. Using a spark plug socket, carefully remove the old spark plugs.
4. Inspect the spark plugs for wear; replace them with new ones if they show any signs of damage or excessive wear (gap them as per specifications).
5. Reinstall ignition coils and reconnect electrical connectors.

4. Check and Repair Fuel System Issues

Sub-steps:
1. Inspect the fuel system for any leaks or damaged components.
2. If the fuel is of poor quality, drain the tank and replace it with high-octane fuel as recommended by the manufacturer.
3. Consider using a fuel system cleaner if necessary.
