Precautions for engine inspection:

1. The engine dipstick and oil filler cap must be installed correctly, otherwise the engine operation will be affected.

2. The air inlet hose should not be broken, and the clamp should be installed and fastened. Because air leakage will affect the signal of air flowmeter or intake pressure sensor, thus affecting the fuel injection quantity, making the engine unstable at idle speed, easy to stall, and poor power and acceleration performance.

3, vacuum tube can't break, kink, can't insert the wrong. The wrong insertion of vacuum tube will make the engine idling unstable, and even make the cylinders work irregularly alternately.

4. The fuel injector shall be fitted with comfortable stickers and the sealing ring shall be intact. If the installation is uncomfortable or the sealing ring is damaged, the upper installation seal will leak oil, causing serious accidents, and the lower seal will leak air, reducing the vacuum degree of the engine and causing poor operation. ?
