Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Clean Air Intake

Remove the air intake duct to access the throttle body.
Inspect for any blockages or leaks; replace any damaged components.
Clean the throttle body using throttle body cleaner and a soft cloth; ensure the butterfly valve operates smoothly.

3. Test and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Release fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the filter and install the new filter, ensuring correct orientation (inlet/outlet).
Reconnect the fuel pump fuse and check for leaks before starting the engine.

4. Replace Spark Plugs and Ignition Coils

Remove the engine cover to access the spark plugs.
Carefully disconnect the ignition coil connectors.
Remove the ignition coils and spark plugs using a socket wrench.
Install new spark plugs (tighten to manufacturer specifications) and replace the ignition coils.

5. Reassemble and Reconnect Battery

Reinstall the air intake duct and any other components removed during the repair.
Reconnect the battery terminals.
Start the engine and allow it to idle to ensure all systems are functioning properly.
