Solution

1. Preparation

Gather tools and materials needed: OBD-II scanner, fuel pressure gauge, basic hand tools (sockets and wrenches), and a cleaning solution designed for fuel injectors.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clean the Fuel Injectors

a. Use a Fuel Injector Cleaning Kit

Connect the cleaning kit to the fuel rail following the manufacturer's instructions.
Ensure the engine is off and the battery is disconnected for safety.

b. Introduce the Cleaning Solution

Pour the injector cleaning solution into the kit reservoir.
Reconnect the battery and turn on the ignition without starting the engine to build pressure in the fuel system.

c. Start the Engine

Start the engine and let it idle for the recommended time specified by the cleaning kit instructions.
Monitor the engine for any abnormal sounds or behavior during the cleaning process.

3. Final Checks

After cleaning, turn off the engine and disconnect the cleaning kit.
Reconnect any hoses or connections that were removed during the procedure.
Start the engine again and allow it to run for a few minutes to clear any residual cleaning solution.
