Dacia Sandero hesitates and jerks under acceleration
Discussion
Hello everyone,
I've been having an issue with my 2011 Dacia Sandero (petrol) for a while now.
The car starts to hesitate and lightly jerk when I accelerate more firmly. They're not violent jerks; it feels more like the engine is hesitating and the car starts to shudder slightly, almost as if I'm driving over small bumps.
Here's what I've noticed:
When I accelerate very gently, the problem is hardly noticeable.
As soon as I press the accelerator a bit more, the car hesitates and starts to jerk lightly.
At a constant speed, the car drives perfectly fine.
It happens mostly in 3rd and 4th gear, but occasionally in 2nd and 5th as well. It seems to occur mainly when the engine is under load.
We've connected the car to a diagnostic scanner, but there are no fault codes, and the check engine light is not on. The spark plugs have been inspected and appear to be in good condition.
Has anyone experienced something similar or have any ideas where I should start looking? I've heard it could be the ignition coils, a fuel delivery issue, or perhaps a sensor, but I'd rather not start replacing parts without a better idea of the cause.
Any advice would be greatly appreciated. Thanks in advance!
