After replaced IAC still wouldnt idle so installed IAC spacer and it runs pretty good at 12 BTDC, TPS is set low, fuel pressure about 35-40 psi.
Only thing now is when stopping, put the clutch in and brake, when the RPMs hit bottom it will die if I dont feather the gas. Tried to adjust IAC spacer screws to let more air in but then the idle gets worse.
