Iveco's acceleration is weak, but it stinks.

Carbon deposition in the car, air in the high-pressure oil pump, and fuel pump failure. According to the query of Iveco official website, it is known that the acceleration of the vehicle is weak and there is an odor because:

1, car carbon deposit will lead to weak acceleration and low idle speed. If this happens, just clean the throttle.

2. There is air in the high-pressure oil pump. If there is too little fuel in the fuel tank of the car, the high-pressure oil pump will suck in air when it sucks the gasoline in the fuel tank, so that the fuel cannot be injected into the cylinder and the car cannot be started. You can loosen the connecting nut between the oil pump and the oil injection valve to release air.

3. If the fuel pump fails, you can apply soap to the damaged part, separate the damaged pump membrane from the intact pump membrane, and stagger and reinstall the damaged part. 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.
