I have a TATA Nano CX 2010 (19000 kms). After an upshift car hesitates to accelerate for 3-4 seconds then accelerates smoothly. This happened on every upshift. This problem was fixed for a moment after refueling then it started happening again. Then changed the Main relay and everything was back to normal again. Any idea what could be the issue here?
Change the fuel filter (if equipped) and pressure test the fuel pump. Does this car have a throttle cable or an electronic throttle body?
If you rev it up while parked, in neutral, does it still hesitate?
@inthrustwetrust yes sir it is a throttle cable and it wont hesitate when parked in neutral, it just happens randomly for now the car is fine. i will sure get the fuel pump tested thankyou so much. 🙂
