Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to ensure safety.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt or damage.
If dirty, clean it with compressed air or replace it with a new one.
Reinstall the air filter and secure the housing cover.

3. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Ensure that the throttle plate moves freely without obstruction.
Reattach the air intake duct securely.

4. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position without starting the engine to check fuel pressure.
Compare the reading with the manufacturer's specifications (usually between 50-60 psi for many models).
If pressure is low, replace the fuel pump as per the manufacturer's guidelines.

5. Inspect and Replace Ignition Components

Remove the engine cover if applicable.
Disconnect the ignition coils and remove them using a socket set.
Inspect the spark plugs for fouling or wear; replace if necessary.
Install new spark plugs and reassemble the ignition coils.
