I bought the car about around 2 months ago and now i'm having some issues. the check engine light has come on and the engine power reduced light as well. the codes that came up were: p0121 (throttle position sensor) and p2135 (unknown at this time). took it back to the dealer and they couldn't run down exactly what is going on with it. does anyone know if there are other torrents doing this or if there is something we can do to figure out what exactly is going on. any help would be apprieated.
