Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake hose connected to the throttle body.
Use throttle body cleaner and a clean cloth to clean the throttle plate and surrounding areas.
Reassemble the air intake hose and ensure it is securely fastened.

3. Inspect and Clean the MAF Sensor

Locate the MAF sensor in the air intake system.
Carefully disconnect the electrical connector and remove the sensor.
Use MAF sensor cleaner to spray the sensing element without touching it.
Allow the sensor to dry completely before reinstalling it.

4. Check and Replace Spark Plugs

Remove the ignition coils from the spark plugs.
Use a socket wrench to unscrew the spark plugs from the cylinder head.
Inspect the spark plugs for wear; replace them if they are worn or fouled.
Install new spark plugs with the manufacturer-specified torque (typically around 13 ft-lbs).

5. Inspect the Fuel System

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (without starting the engine) to check the pressure.
If the pressure is below manufacturer specifications, check the fuel pump and fuel filter for issues.
