Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off and cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Engine Oil

Sub-steps:
- Remove the oil drain plug using a socket wrench and drain the old oil into a suitable container.
- Replace the oil filter using an oil filter wrench; lubricate the rubber O-ring of the new filter with a bit of new oil before installing it.
- Reinstall the oil drain plug and torque it to the manufacturer’s specifications (typically around 20 ft-lbs).
- Fill the engine with new oil (check the owner’s manual for the correct type and capacity, usually 0W-20 or 5W-20).
Tools Required: Oil drain pan, socket wrench, oil filter wrench, funnel.

3. Replace Spark Plugs

Sub-steps:
- Remove the ignition coil connectors and unbolt the coils.
- Use a spark plug socket to remove the old spark plugs.
- Inspect the new spark plugs for proper gap (typically around 0.043 inches).
- Install the new spark plugs and torque them to specifications (around 13 ft-lbs).
- Reinstall the ignition coils and connectors.
Tools Required: Spark plug socket, torque wrench, ratchet.

4. Inspect Timing Components

Sub-steps:
- Remove the engine cover if applicable.
- Inspect the timing belt/chain for tension and wear; replace if frayed or damaged.
- Check the timing marks to ensure they align correctly.
Tools Required: Various socket sizes, timing light (if applicable).
