[QUOTE="69mach03, post: 8091455, member: 11021"] Converting from EFI to Carb on my '94 Cobra - Need Intake and Carb suggestions ASAP! I've spent weeks trying to get the car running right. It won't idle down past 1400 RPM without going into a radical lope, i.e. searching / hunting, until it stalls. I've got a TwEECer and Zeitronix wideband on the car.
