EFI Pu Sang idling is unstable, and it is easy to stall!

There are many problems in the oil circuit. In fact, the throttle valve of 4S shop can be tried out. If this is not the problem, it can be removed. If the throttle valve is not round, it will be unstable at idle speed and will not change after starting. It is recommended to check the gasoline pressure.

First: the throttle and the throttle idle stepper motor should be cleaned, and then started to set the idle speed. Under normal circumstances, just clean it up and don't need a new one.

Second: check whether the spark plug, high-pressure cylinder pipeline and ignition coil are damaged and whether the spark plug has too much carbon deposit.

Third: check whether the gasoline pump has pressure relief and measure it with an oil pressure gauge. Check whether the gasoline filter is too dirty or water causes failure. Check whether the air filter element is blocked.
