So lately my car has been doing something very odd. It always starts up fine, no hard starts, everything runs fine electrically, but once in a while after shutting down and I go to start up again it will be like as if the battery isn't even connected. Then all I do is pop the hood, fiddle with the positive cable a bit, then it starts right up like as if nothing was ever wrong with it. Anyone know what can cause something as abnormal as this and why something as simple as fiddling with the positive cable will fix the problem? Battery is a Duralast and the negative battery connector was replaced recently. If you need anymore info feel free to ask.
