Iveco 2000 rpm is only 80 hours.

The reasons are: car carbon deposit, air in high-pressure oil pump and fuel pump failure. The solution is as follows:

1, car carbon deposit: after carbon deposit is generated, it will lead to weak acceleration and low idle speed of the car. If this happens, just clean the throttle.

2. Air enters the high-pressure oil pump: the high-pressure oil pump is connected with the oil injection valve. If there is too little fuel in the fuel tank of the car, the high-pressure oil pump will suck air when it sucks the gasoline in the fuel tank, so that the fuel is not enough to be injected into the cylinder and the car cannot be started. Solution: Loosen the connecting nut between the oil pump and the fuel injection valve to release air.
