Have a 2.8l 5 speed getrag 88 Fiero GT. noticed that when i was at a red light, my idle was a little loopy (normal) pulses from 1100 to 900 and back in 1 second intervals, but when it surged down to 900 my volt meter would go down with it a tad...do i have a bad ground somewhere? I read on this forum somewhere (though i cant find it again) that someone added a ground strap from the positive terminal of the battery to one of the bolts on the blocks. and that improved his idle and performance...i dont know, thoughts?
