Passo Model 14
Mileage 38K+
Problem: 1) on 2nd or third gear with lower speed, there is some sort of knocking or engine vibration noise ( i am not sure about the sound but engine losses the power for sure ).
To avoid this, I used to take off my feet from the acceleration paddle for 4 to 5 sec and then start accelerating again to avoid this engine misbehaviour.
2) usually on third gear, on a constant rpm, there is sudden change in pick with a little jolt and increase in car acceleration roughly after 10 sec.
All of the above issueswere not observed before 1k km.Overall, it feels like engine is running under power but at the same time i have been getting fuel average of around 18 to 20. I am not sure what engine oil was used by the owner but currently, i am using shell hx7 5w30.
Thanks
