My check fuel cap light came on. I twisted the cap and disconnected the battery to reset. After a couple of days the light came on again. I decided I better just get a new cap. But before I got the new cap the Check Engine Light came on. Are the two connected? Is the check engine light on because of the check fuel cap light? I guess I can go to Autozone tomorrow and get a reading but the a-holes over there don't want to have to walk outside to help a customer and that is why I do almost all my trading with NAPA. Thanks
