Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during the repair.

2. Replace Spark Plugs

Remove the spark plug wires or ignition coils (depending on engine configuration).
Use a socket set to remove the old spark plugs.
Inspect the old spark plugs for signs of fouling or wear.
Install new spark plugs, ensuring they are gapped correctly according to manufacturer's specifications.
Reconnect the spark plug wires or ignition coils.

3. Inspect and Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body and ensure the throttle plate moves freely.
Reassemble the intake duct securely.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter and relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the old filter using appropriate line disconnect tools.
Install the new fuel filter, ensuring correct orientation and secure connections.

5. Inspect for Vacuum Leaks

Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
Use a smoke machine or propane enrichment method to identify any vacuum leaks.
Replace any damaged hoses as necessary.
