Only when I accelerate , lately it has been happening every time I accelerate thens dies off, I did a search on 240SX.org and someone said that the tranny mounts were worn and they replaced with Nismo mounts. Now if they are actually the mounts will the Nismo fit an auto tranny? It's more noticeable when I accelerate hard from a stand still or when cruising and opened up at open throttle.
