Thank Daniel,but the thing is when you are cranking it doesn't but when you push the throttle manually to fully closed position that's when it cranks then when you open the throttle little by little like you are accelerating it goes off as soon the throttle opens
Thats it,the vehicle is not responding when you depress accelerator pedal if it is on idling,it goes off once you press the accelerator pedal

it may need computer scanning although the problem occurs normally due to faulty airflow sensor. i can refer u to diagnosis specialist that u can contact thru 0735314811
