Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuel Filter

Tools Required: Fuel line disconnect tool, socket set, catch pan
Locate the fuel filter (usually along the fuel line).
Use the fuel line disconnect tool to detach the fuel lines from the filter.
Remove the mounting bolts holding the filter in place.
Install the new fuel filter in the same orientation as the old one.
Reattach the fuel lines securely.

3. Inspect Ignition Components

Tools Required: Socket set, torque wrench
Remove the engine cover to access the ignition coils and spark plugs.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and inspect for cracks or damage.
Check spark plugs for wear; replace if the electrodes are worn or if they show signs of fouling.
Reinstall the ignition coils and reconnect the electrical connectors.

4. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set
Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Ensure that the throttle plate moves freely without restrictions.
Reassemble the air intake duct securely.
