1972 911T High Idle

Fuel System

Vehicle Information: Model: 911 T; Year: 1972; Body Type: Coupe; Engine (type, size, modifications): 2.4 MFI; Total Mileage: 76000;

The car has an erratic idle problem that I can't seem to isolate. Most of the time after it's fully warmed up it idle's at 2000 rpm. I'll drag the clutch when stoping and bring it down below 1000 rpm and then it takes off again to 2000. Other times I'll drive the car and it barely idles at all, it's so low that the red charging light comes on. However, the car accelerates like a banshee and does'nt skip a beat. Thought I had a vacumn leak, but couldn't find one. Any ideas?
