Check whether the air intake hose has cracks or perforations, whether the clamp is loose, and whether the air intake pipe bolts are loose. If the air inlet hose is found to be ineffective, it should be replaced. If the clamp is found to be loose, tighten the clamp bolt. If the bolt is found to be loose, tighten the bolt to ensure that the air intake system does not leak.Editor/Baohongying
