Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Engine Oil

Tools Required: Oil filter wrench, socket set, drain pan.
Instructions:
1. Place the drain pan under the oil pan.
2. Remove the oil drain plug and allow old oil to drain completely.
3. Replace the drain plug and tighten to manufacturer specifications (usually around 20-25 lb-ft).
4. Replace the oil filter using the oil filter wrench.
5. Refill the engine with new oil that meets specifications (usually 5W-30 or 0W-20, check owner's manual).

3. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Instructions:
1. Remove the ignition coils from each spark plug by disconnecting their electrical connectors and unscrewing them.
2. Use the spark plug socket to remove the old spark plugs.
3. Inspect the old spark plugs for wear; replace if they appear corroded or damaged.
4. Install new spark plugs, ensuring they are gapped correctly.
5. Torque the new spark plugs to the manufacturer's specifications (typically around 13-15 lb-ft).
6. Reinstall the ignition coils.

4. Fuel System Cleaning

Tools Required: Fuel system cleaner, fuel pressure gauge (if needed).
Instructions:
1. Use a fuel system cleaner by adding it to the fuel tank as per the product instructions.
2. Optionally, check fuel pressure to ensure the fuel pump is functioning correctly.
