Misfire at start-up

Hey Guys,
Have a 92 Camaro with an LSx-T56. Ran really good....for the first week after I bought it. Now I have a misfire at start-up. Goes away after 3/4 minutes. Interestingly, not just when cold. I can drive it around for a bit with no problem. Turn it off and start it again and it will miss again for a bit until smoothing out.
Just starts dumping fuel.

OBD1 port so I haven't figure out how to scan it yet.

Any thoughts?

Thx

It should have a OBD II port somewhere. Sometimes it will be mounted on the passenger side, just depends on the harness and where whoever installed the harness decided to mount the port.

Do you know who made the harness?
