Somewhat unexpected - sudden speed

Post by z4lover »

I have noticed on and off that when driving, if I pull off the accelerator, the car seems to slow for a second (as expected) then suddenly speeds up. It feels as if maybe one of the brake discs suddenly lets go at the back (as if it was dragging against it for a bit).

I am not on the brakes and the clutch is fully engaged when this happens.

Anyone else experienced this?

Not an auto is it?

The torque convertor can play strange tricks on you sometimes.
