I have an 81 280zx - all stock. It starts fine warm or cold, and idles fairly evenly (slow oscillation between 700 & 800 rpm), but during warmup, the idle speed drops from 750 rpm to 500 rpm, and there is noticeable hesitation when accelerating (I keep the revs below ~ 3000 rpm until warm anyway).
Any ideas what could be causing this problem?
Thanks,
Darryl
