Well, after the B&G fuel treatment, my traverse runs better than it ever has. I bought it used, so it's amazing how smooth it's running, startup hesitation is also gone. Something which is now more noticeable though is that on the highway with cruise control on, it occasionally has a hiccup, like it loses fuel or something, so there may yet be a fuel pump problem. A friend who is a master mechanic said my vehicle is too new to have fuel pump issues, I don't know. We will see what happens. I'm looking for a mechanic to diagnose it.
