Hello,
I was out for a ride recently and all of a sudden my idle went from steady 900-1000 to varying 1000 to 1500-1800. I checked for vacuum leaks, checked the base timing and made sure the tps was at .98. I am running a 75 mm/ma and a 70 mm/tb, gt40 heads 24 lb inj. a ford "F" cam and a Diablo chip.
Any idea's ??
