Yesterday while driving my car started pulling and reving..my mom said I needed oil so I put it in and it stoped alot....it only did it a little while going home...I just pulled into school 10 min from home(freeway) and it started doing it bad...people are saying it could be the vss sensor...which I have no idea what that is....buuuuut I have no money right now to fix it...so is it bad to continue driving it or will I mess it up more? And also I had the whole flashibg d4 light before and a machanic said to drive in d3...but another machanic said its bad...is it?
Thank you
