I have been having an issue that is intermitant. This just started happening where when I go to start my truck the starter just spins and doesn't engage the flywheel. Then I let off the key and try again then it engages like it should and the truck starts up. The truck did just sit for about 2 months prior to this happening. Also not sure if this is related but every now and again my radio loses all of its presets in the middle of driving. Could this be a loose battery connection or corroded connection?
