It is most likely one of two things....

1) Vacuum leak.  You said you checked, but I'd check again.  You can also
pinch the PCV hose with pliers and if the idle changes (can't remember if it's
up or down), you definitely have a vacuum leak.

2) Bad ground.  This is less likely since it ran OK before.  But...  I ran
into this with my first engine swap.  Check the grounds at the intake
manifold.  If those were left off it would act really strange and be difficult
to keep running.
