Thread: Don't Top Off !!

I've got a 99 Prizm that has had the engine light on for years because of that evaporative fume recovery whatchamahoozit. I clear the code and it comes right back. I've always stopped after the pump shut off so I don't know what caused the problem but mechanics have told me to ignore it. Of course then you never know when a new code is thrown so I try to check them occasionally, whenever I remember it, like maybe three years ago.
