Well swapping the 3900 did stop the fluctuations but still no dice and i've swapped out about 10 different 4007's from 2 different batches.
The thing that's throwing me for a loop is i'm not getting any change in voltage off pin 10 of the 3900.I'm assuming i should be seeing the voltage i'm feeding that pulse input and able to see pin 10 go high and low?
