Hello，I have a question!
I have a question about my car.
I have a MK2 2.0AT FOCUS, has modified the NEW MAN 258 HIGH CAM. I use the sct advantageIII custom tune my car.
Now my question is. When the car is at idle ,the air-fuel ratio is 14.7. Vehicles normal. No exceptions.
When the transmission working on D mode,accelerated moving forward five meters, and then quickly Depress the brake pedal to make the car stop , RPM will fall 650, the car will shake, and sometimes, the car will automatically turn off.
Does someone know how to solve this problem?
