Iveco can't accelerate at 2000 rpm.

The reasons why Iveco can't accelerate at 2000 rpm are: carbon deposit in the car, air in the high-pressure oil pump and fuel pump failure. The solution is as follows: car carbon deposit: after carbon deposit is produced, it will lead to weak acceleration and low idle speed. If this happens, just clean the throttle. 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. Failure of fuel pump damage: Soap can be applied to the damaged parts, the damaged pump membrane can be separated from the intact pump membrane, and the damaged parts can be staggered and reinstalled. If the gap at the rupture is long, cut it into the shape of a circular diaphragm with a film or waterproof cloth and sandwich it between the diaphragms. At this time, you can only drive at a low speed, and then find professional maintenance personnel to repair or replace the fuel pump.
