so as the title says, i have a 2003 hyundai sonata and when i come to a stop the car jerks. Some times it will not do it for an entire day and others it will do it 10 times while i am at a stop sign. The RPM's seem to drop every time it jerks but not to the point where it is going to die or anything like that. Other than that it drives perfectly, doesnt seem to lose any power once i get going and the speed always matches the rpms.

ayone have any ideas of what could be up? my father seems to think it may be the one of the speed sensors but im not sure because it only does it at a complete stop and not when i am moving and it up shifts and down shifts fine.

Check the air inlet to make sure it's not obstructed. If the filter is dirty or obstructed, it could still drive okay at speeds, but when idling, it could have a hard time getting air in, thus causing the RPM to drop and the engine to jerk because it is on the brink of dying from lack of airflow.
