Zhengzhou Nissan d22 cold car will stall and the acceleration will be weak.

In this case, please check the gasoline pressure first, whether the gasoline pump has pressure relief, and replace the gasoline pump!

Check whether there is too much carbon deposit in the intake pipe, valve and injector, which causes the carbon deposit to absorb the fuel in the mixed gas when the car is cold, resulting in the situation that the mixed gas is too thin! Please clean up the carbon deposit in the air intake system!
