i had my p28 hooked up to a jumper harness and the car ran fine. then i just installed a V-Afc 2 that was already connected to another harness. my car starts to buck when i'm letting off going into to first gear. it did it a couple times on me and the car even shut off. i wanted to know if there is some how to fix it with the VAFC because my car isn't throwing any codes for sensors.
