Ok good so i'm not crazy then. I was thinking back, I turned cap last time i filled up and i remember it clickin when i turned it. But when i went to check it was loose, it's been pretty hot/muggy in nyc recently. I wonder, it seems there's more than meets the eye *transformers reference* when it comes to gas cap, I know it's been discussed before, i think even a recall at one point. I would love for others to chime in with possible remedies to get my enginel light to turn off...
