Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, throttle body cleaner, torque wrench.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter for dirt or damage. If dirty, replace it with a new one.
Reassemble the air filter housing and secure it properly.

3. Check Fuel Pressure

Connect the fuel pressure gauge to the fuel rail service port.
Turn the ignition to the ON position (do not start the engine) and read the pressure.
If the pressure is below the manufacturer's specification, inspect the fuel pump and replace if necessary.

4. Clean Throttle Body

Disconnect the throttle body connector and remove the throttle body using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body until clean.
Reinstall the throttle body and reconnect the electrical connector, ensuring all bolts are torqued to the manufacturer’s specifications.

5. Inspect and Replace Spark Plugs

Remove the ignition coils by unbolting them and pulling them out.
Use a socket set to remove the spark plugs.
Inspect the spark plugs for wear; replace if necessary with OEM-spec plugs.
Reinstall new spark plugs and ignition coils, securing them properly.
