Acceleration is incredibly******** at low gears. This symptom is hit or miss, sometimes happening and sometimes not, and it seems that if I work the clutch delicately enough, I can pretty well minimize the problem. But it is still a pretty big problem regardless. Normally the********** disappears after shifting into 2nd gear, but it's always gone by the time I hit 25 or 30 mph. Possibly related but probably not, the headlights also grow steadily dimmer as the car sits at idle. The moment the accelerator is touched, the lights fire back on. Any ideas?
