since the problem appears to be in the open loop time period, I would check the temp sensor.
also, back presure, or exhaust flow rate will affect the 02 sensor readings, without the cats, the ecm would need to be reprogrammed.

That's what I was thinking with my earlier post about the friend removing his cat and it throwing a code I forgot the word for it BACK PRESSURE. Glad you cleared that end up for me at least.

Turned out to be plenum gaskets. I took the long way and completly removed the plenum instead of raising it and snapping new ones in place. Put a straight edge to it and found it to be straight. The rubber seals were shrunk and ridgid. It would leak when cold, but sealed somewhat when warm. That explained the "lazy" when cold. Thanx for the help.........Arnie
