Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean the Throttle Body

Remove the air intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Ensure that the throttle plate moves freely without obstruction.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (refer to the vehicle manual for specific location).
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect fuel lines from the filter using a line removal tool.
Install the new fuel filter, ensuring correct orientation.
Reconnect the fuel lines and pump relay.

4. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Remove spark plugs using a spark plug socket, inspecting them for wear or carbon buildup.
Replace with new spark plugs, torquing to manufacturer specifications (usually around 13 lb-ft).
Reinstall ignition coils securely.

5. Check for Vacuum Leaks

Inspect vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to identify leaks.
Replace any damaged hoses and ensure all connections are tight.
