A few months ago my tachometer started to jump when I was accelerating, normally it was during highway acceleration a slow acceleration wouldn't do it. I hooked up a computer to the car to read the code and it said my crankshaft position sensor was bad, so I replaced it. Well after a few months it has started doing it again, and I get the same error code. So I think there has to be something else causing this as well, someone said they thought it could be a transmission speed sensor. But they are a novice at car repair as well, I do kind of believe it though because the tachometer normally jumps at the same time as my transmission is shifting between gears. Is there a way I can narrow it down to a component?
