Gas cutting and stopping at idle

brothers help me for the sake of Allah, I'm about to go nuts. I changed the brain of the car recently, the world cost. I took care of it, I took the car. Now the car is running, there is no problem walking, but it is not clear when it will be done, "It cuts gas for 3 seconds like entering the cutter, I stick to the seat you know, then it continues to help as if it wasn't the gas cutter." We connected it to the Bosch brand device. The crankshaft sensor reader malfunction and the penetration in the flow meter are low, the flow meter does not have such an effect because I changed it before it broke. Low-traction fuel consumption and flow meter. However, I did not solve the other. If anyone knows what happens, get help.

I guess the car's diesel makes such troubles if my brother crankshaft sensor is faulty. If the new flow meter may have malfunctioned, mass production parts may eventually come to you with the factory patient.

Yes, diesel brother. Today I will leave the vehicle only to the service that repairs the peugeot. Let's see what happens. Well, he was very annoyed now. I hope this will be the last & nbsp;
