Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace Fuel Filter

Sub-steps:
- Locate the fuel filter in the fuel line.
- Use a wrench to disconnect the fuel lines from the filter, taking care to catch any spilling fuel.
- Remove the old filter and install a new one, ensuring the direction of flow is correct.

Safety Warnings: Allow any residual fuel to evaporate; work in a well-ventilated area.

3. Replace Spark Plugs

Sub-steps:
- Remove the engine cover if necessary to access spark plugs.
- Use a spark plug socket to remove the old spark plugs.
- Inspect the old plugs for damage or carbon buildup.
- Gap the new spark plugs to manufacturer specifications.
- Install the new spark plugs and tighten to the recommended torque (usually around 13-15 lb-ft).
Tools Required: Spark plug socket, torque wrench.
Safety Warnings: Ensure engine is cool before working on spark plugs.

4. Clean Throttle Body

Sub-steps:
- Remove the air intake duct to access the throttle body.
- Use throttle body cleaner and a soft cloth to remove carbon buildup inside the throttle body.
- Move the throttle plate gently to clean both sides.
- Reassemble the air intake duct securely.
Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
