My car is jerking revving the RPM needle is bobing how do i make this stop?

Hi Lili, That's my daughters name! So, the vehicle may be going into limp mode, due to transmission failure, fuel delivery failure, or a number of other faults. To understand this issue, you are going to need hands-on diagnosis. If you have a scan tool and post the codes back here I can try to point you in the right direction, otherwise, the repair facilities in the link below will have the ability to get your car fixed right. http://repairpal.com/nissan-within-10-miles-of-bakersfield-california-93304
