Default rough idle at start on 94

For a long time I was chasing a miss which has been fixed but since then, I've developed a new problem.
Not long after that I noticed that my car took two attemptes to start it (rather than starting off on the first try like normal). Then one day I could feel the engine surge and choke. It would shudder, surge, and then almost stall, like it wasn't getting gas. Eventually it would smooth out after 20 or 30 seconds, and drive normally. This happened about once a week aft first, but now it does it to a lesser degree with every start.
In the last 6 months I've changed
Opti
wires and plugs (twice first with OEM and then with high performance parts)
fuel filter
fuel injectors (from FIC)

Any ideas oh wise ones?
