Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working.
Allow the engine to cool before beginning any work.

2. Inspect Air Filter

Remove the air filter housing cover.
Take out the air filter and inspect for dirt or blockages.
Replace with a new air filter if necessary.

3. Check and Replace Fuel Pump (if needed)

Locate the fuel pump access panel (usually under the rear seat).
Disconnect the fuel lines and electrical connector from the pump.
Remove the pump assembly and replace it with a new one.
Reconnect fuel lines and electrical connectors, ensuring no leaks.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
Reassemble the intake duct and check for secure connections.

5. Inspect Ignition Components

Remove spark plug wires and inspect for cracks or wear.
Replace worn spark plugs with new ones according to manufacturer specifications.
Test ignition coils with a multimeter to ensure they are within specifications.
