93 Still Runs Really Rough on First Start-up 200

I posted a few weeks ago about this and have tried a few things.

Our 93 wagon, only on first start up in the morning, starts up normally, then, if I give it any gas at all, gets really rough, like it's running on two or three cylinders. It doesn't stall or hunt. After about 45 seconds, it seems to run normally under all driving conditions except that the warm idle is a little rougher than usual, but not really bad.

I'd like to fix this before it develops into a bigger problem. So far I've eliminated the ECT sensor, the AMM and the O2 sensor. My testing shows that they are innocent. The OBD does not throw any codes.

Does anyone have any ideas on what else to check?
