ULN2003 new guy needs help

Hello,
I'm kind of new to the basic stamp and even newer to the ULN2003 I
have a circuit hooked up and working but something isn't quite right.
I don't think I'm getting the Torque or RPM that I could be out of
my
stepper motor. and as it turn it's a bit jittery. I think the
problem lies in my BS2sx Code. Can anyone provide me with some
sample code? thanks.
I'm using the 4 data line method I have the i/o lines 4-7 connected
to
the ULN2003 3-6 pins respectively. and pins 11 -14 are connected to
the stepper coils.
The stepping pattern that came with my motor is as follows:
UNL2003 pin 11 12 13 14
coil 4 3 2 1
1 0 1 0
1 0 0 1
0 1 0 1
0 1 1 0
Thanks for any info that you can provide. I don't need any thing
fancy
one direction just something that will work then I can modify the
code from there.
Thanks again
Dave
