ok got in my car one night after work and turned the key and nothing at all.Popped the hood, the lights on hood were bright enough to tell me its not the battery.So I went to the starter,sure enough it was kinda loose.tightened up the starter bolts,it starts to my relief!But they weren't really loose i just snugged them down.Anyway now sometimes have to get the starter really loose to crank her over.then tighten down the bolts and go on.Now is this my starter telling me its going out or what?
