J240ZTurbo Posted December 30, 2010 Share Posted December 30, 2010 Hi Guys , I got an all original red 1983 280zx Turbo with only 69k on it, for some reason the car RPMS change from time to time from 900-1000 rpms to 1100 at idle, also when cruising at a steady pace the car feels it has a little spurk on it, can someone please help me? thanks, Juan.
