Gary, If it's the little plug that has a wire going to it on the bottom side of the engine that would be your neutral safety switch. I think it takes a deep 10mm socket and you can first try to tighten it just a little ( Sorry I'm at work until tomorrow so I don't have my manual for the torque spec) If that doesn't work I replaced the little copper washer seal and it stopped the leak on mine. Nothing falls out when removed it's super easy to do. Hope this helps and hopefully someone that has access to a manual can give you the torque spec for that little bugger. T
