My Tata zest petrol XT model has acceleration issue in sport mode when I drive car around 60-70 km . It suddenly loosing acceleration and power of the car and engin malfunction light turn on. When I stop the car for 2-3 minutes it again running normal with power and acceleration but mode of car is CITY now. After 70-80 km drive engin malfunction light automatically turn off. Please let me what causes this issue . I showed my car to local garage and they told me it is due to Throttle Body sensor issue.
