Random Miss....
OK, here's the deal.
Replaced the injectors a month or so ago. Bosch Design IIIs. Also did a cat-back, and a few minor things (ie. wire looms, EGR temperature sensor).
Car runs real strong, until... Randomly, the thing will just start missing. Very, very noticeable. Put your foot into it -- in park, drive doesn't matter and its very sluggish and rough to accelerate. And then at some point, it stops doing it. An hour ago, I pulled the car out of the garage. Ran fine. Started it back up to pull back in, its doing the miss thing.
No vacuum leaks. All plug wires on tight. Everything hooked up correctly. Honest and truely -- nothing changes it just starts acting up and then corrects itself when it feels like it. Runs fine for a while, then at some point, same thing.
The car may have done this once or twice before the injectors. Honestly, I don't recall.
Planning on putting the car back on the road this week, and obviously need to fix this.

Mine seems to be doing the same thing. Very random missing; One day she drives like a dream and the next I'm unsure of her.
I'm considering buying a replacement ecm. I saw this on another Vette and it did turn out to be the ecm. If it doesn't fix it, I'll have an extra.
