i seem to be having a problem with my tach, when i first got the car in june, everything was fine until later that week. when i start the car it revs up to 3500, and it idles at around 2900. is there anything i can do myself, or is this an issue i should just bring back to the crap dealer and ***** at to get fixed?

 

take it to the dealer thats what a warranty is for
