Urgent! ! Jiangling JMC double-row short-axle truck maintenance experts come in! ! !

I want to ask if your intake branch pipe has been changed, which one has a rigid ring? If it is not a hard intake manifold, please check that the intake manifold will not be flattened by neutral, and it will also make a lot of noise. Check whether the air inlet in front of the throttle is leaking or not installed, but it should not be there, because it will not affect horsepower. Without air filtration, it will only make the car more oyster sauce and increase horsepower, and then ask if the load is the first problem. If yes, check whether the clutch is loaded. Sometimes it slips. Is your water temperature too low? Diesel vehicles can't have low water temperature. Oh, it will affect the horsepower. Just keep the water temperature above medium. Diesel works at high temperature and high pressure, and the temperature cutoff device cannot be removed.
