At low gear and rpm speed oscillates
When the car is in 1st or 2nd at very light to no throttle being applied (1000 to 2000 rpms) the cars speed will slowly begin to oscillate. The speed increases then decreases and the amplitude of the oscillations increase with time (positive feedback).
The only way to break free of the oscillations is to press on the throttle so the car starts to accelerate or press the clutch to break free the engine from the tranny. I haven't dug to deep to find out where the source of this positive feedback is. Anyone else have this problem? It becomes evident in very heavy traffic where the car is moving at a crawling pace.

Some have mentioned that it can happen on the SCs with an oxygen sensor. I felt it a "little" bit when I had mine hooked up. Now I dont seem to notice it at all (with it unhooked). Good luck.

Have you had your mixture checked? It may be running rich.
