FWIW, I've noticed that the check fuel fill inlet indicator commes on after driving 70+ Mph for periods of time longer than like 20 minutes. I suspect there's an issue somewhere (control valve, purge, etc.) but I also notice that a couple of drive cycles on city roads turns it off. This behavior is reproducable. to pass inspection I cleared the code, drove only backroads for a week or so and then got my sticker. Hope this helps some folks to get their inspection sticker as well. Dan
