Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the battery to ensure safety while working with electrical components.
Allow the engine to cool before beginning any work.

2. Inspect and Replace Air Filter

Locate the air filter housing.
Open the housing and remove the old air filter.
Inspect the filter for debris and replace with a new, clean air filter.
Secure the housing back in place.

3. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line (refer to the service manual for location).
Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate tools.
Remove the old fuel filter and install the new one, ensuring proper orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Clean or Replace Throttle Body

Remove the air intake ducting connected to the throttle body.
Clean the throttle body using throttle body cleaner and a soft brush, ensuring the butterfly valve operates freely.
If damaged, replace the throttle body with a new unit.
Reassemble the air intake ducting securely.

5. Inspect and Replace Ignition Components

Remove ignition coils by unscrewing them from the engine.
Inspect spark plugs for wear; replace if they show signs of damage or excessive wear.
Install new ignition coils if needed, ensuring they are seated properly.
