Ok, I have an '82 Camaro and got this car back in November 2012. When I got it, the speedometer was sketchy, it would work for a week and then stop for two weeks and then kick back up and work for another 2 weeks and stop for another few weeks, and as of about 2 months ago, hasn't worked at all. It's just been sitting at about 20mph and doesn't move. I'm trying to figure out if this could be a problem with my speedo cable or with the speed sensor. I don't know a whole lot about cars, so could you also tell me where to find both ends of the speed cable and also where to locate the speed sensor so I can take a look at it in the morning?
