Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect for dirt or damage.
Clean the filter if reusable or replace it with a new one.
Reassemble the air filter housing cover and reconnect.

3. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel 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 correct orientation.
Reconnect the fuel lines and the fuel pump fuse.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior surfaces of the throttle body.
Reattach the air intake duct securely.

5. Inspect and Replace Spark Plugs

Remove the engine cover if necessary to access the spark plugs.
Use a socket set to remove the spark plugs.
Inspect the plugs for wear or carbon buildup; replace them if necessary.
Torque new spark plugs to manufacturer specifications (usually around 15 ft-lbs).

6. Test and Replace Ignition Coils (if necessary)

Disconnect the electrical connector from each ignition coil.
Remove the coil using a socket set.
Test coil resistance with a multimeter; replace any that are out of specification.
Reinstall the ignition coils and reconnect the electrical connectors.
