Random Miss/Stumble

'86 L98.
Just installed new injectors, catback, EGR temp sensor. Car runs nice and strong, but occasionally and randomly, the car will develop a miss. Only remember it doing this after the injectors.

No vacuum leaks, plug wires on tight. By random -- the car will run great. Go out to start it an hour later and it does it. Couple hours later, it runs fine again.

I'm at a loss. Thinking it could be a bad injector, dying coil, yada yada.. Ideas?
