1990 MX-6GT w/ upgraded IHI turbo, MSD Blaster 2 coil, HKS intercooler piping, 2 1/2 inch turbo back exhaust. After the car has warmed up the idle starts to flop between 650 and 800rpm. Occassionally shutting off, then the car won't start after that. I'm thinking maybe its the ignitor fot the coil. Any other ideas before I start going nuts.
