alright well here's the specs on the car

1991 hatchback 168,xxx miles, manual
the engine starts up right away every time
it also idles at a normal level (around 600-700)

but recently i'll be driving along, come to a stoplight or sign and i'll hit the clutch put it in neutral drop out the clutch the engine revs down but then it will either go all the way down and kill or it will go almost all the way down and bounce around and then die and i can't figure out what's wrong any input is appreciated.
