Solution

1. Preparation

Gather all tools and parts needed.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical shorts or shocks.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the existing air filter and inspect it for dirt or damage.
If dirty, clean the filter or replace it with a new one according to manufacturer specifications.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter and relieve fuel system pressure.
Disconnect the fuel lines using a line removal tool.
Remove the old fuel filter and install a new one, ensuring the flow direction is correct.
Reconnect the fuel lines securely.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner onto a clean cloth and gently wipe the throttle plate and surrounding areas.
Reassemble the intake duct and ensure all connections are tight.

5. Replace Ignition Components

Inspect each ignition coil and spark plug.
Remove the old spark plugs using a spark plug socket and replace them with new ones, ensuring to torque them to the manufacturer's specifications.
Replace any faulty ignition coils as needed.

6. Inspect and Replace Vacuum Hoses

Check all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with new ones, ensuring proper routing and secure connections.
