I left town for a week and just returned today. Started my 4runner up in the garage and backed out. I smelt a burning plastic, but didnt think anything of it. This might be unrelate, but something I noted. Once I started to drive, there was little vibrations when the 4runner was stopped at red lights. It was almost like my seat had small rumble to it when I stopped at lights. When in Neutral, it goes away. I went for a drive again and it seemed like it went away and then came back again when I stopped in my driveway. Any ideas? Never noticed this until it sat in the garage this past week.
