First, you need to observe the fuel cut-off for the applicable engine, block the drive wheels, and set the parking brake. Then, please place the vehicle's transmission in Park or Neutral, turn the air conditioning (A/C) OFF, cycle the ignition from OFF to ON, apply and hold the brake pedal for the duration of the procedure, and start and idle the engine. Finally, you should accelerate to wide open throttle (WOT), and release the throttle when fuel cut-off occurs.
