Once a mechanic changed the default RPM settings by changing the screw position of the throttle body. After that the setting is always disturbed, sometimes I fasten it and it feels higher rpm and vice versa.
There is no rpm meter in Mehran so I can't know the actual rpm value.
Please guide me how can I adjust it to default or correct position?
P.S. My Mehran is 2016 model. The mechanic changed the throttle screw because I told him the car is jerking. Now I came to know mechanics do false solution for engine vibration by increasing the rpm.
