I honestly have no clue what your post says... are you shifting while pedaling? You always need to be pedaling to shift.

it sounds like your freewheel or freehub is sticky and is causing the chain to pull the derailleur up and back. but a little punctuation and perhaps a better description or picture may work wonders.

we ain't too big on aolese in these here parts...
