Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Remove the fuel pump relay and check the fuel pressure by connecting the gauge to the fuel rail.
If pressure is low, replace the fuel pump. If pressure is adequate, proceed to the next step.

3. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner onto the throttle plate and use a soft cloth to wipe away carbon deposits.
Reassemble the air intake duct securely.

4. Ignition System Check

Tools Required: Multimeter, socket set.
Remove spark plugs and visually inspect for wear or fouling.
Test ignition coils for proper resistance using a multimeter.
Replace any damaged spark plugs or ignition coils as necessary.

5. Final Assembly

Reconnect the battery.
Clear any error codes using the OBD-II scanner.
