Mitsubishi forklift suffered a serious setback when releasing the throttle.

There are generally four reasons for letting go of the throttle.

The reasons for the frustration of loosening the throttle are: there are more carbon deposits in the throttle, nozzle and air inlet; The fuel quality is unqualified and the combustion is insufficient; Spark plug and ignition coil failure, resulting in cylinder loss; Engine torque does not match transmission oil pressure.

The solution to the frustration of releasing the throttle is to clean up the carbon deposit in the throttle, nozzle and intake pipe; Replace qualified fuel; Replace the spark plug and ignition ring; Change transmission oil. The function of the throttle valve is to control the throttle opening of the engine, control the air intake, and control the oil quantity through the computer, thus controlling the engine speed.
