Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace Air Filter

Remove the air intake cover using a socket set.
Take out the air filter and inspect it for dirt and blockages.
If dirty, replace with a new OEM air filter.
Reinstall the air intake cover securely.

3. Check and Replace Spark Plugs

Remove ignition coil covers if applicable.
Disconnect the ignition coils and remove them using a socket set.
Remove old spark plugs using a spark plug socket.
Install new spark plugs with the recommended torque (usually around 12-15 lb-ft).
Reinstall ignition coils and covers.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Reassemble the intake duct securely.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail's test port.
Start the engine and observe the pressure reading; it should match manufacturer specifications (usually around 40-60 psi).
If pressure is low, consider replacing the fuel pump or checking for blockages in the fuel line.
