Stalls when cold, idles fine after only 1min warmup.

Short version:
When cold, it starts fine, but where it would usually hover around 1700rpm until warmed up, it now gradually drops lower and lower and stalls in a matter of 3-4 seconds.
Tapping the throttle keeps the engine running easily enough and after only a minute or so, the temp gauge hasn't really moved, it will idle fine at 1500 or so.
It seems to run/drive fine. No CELs. Problem arose after rinsing parts of engine. Checked/dried spark plugs & main electrical connectors. 93 EJ22T.
More info:
If the engine gets fully warmed up, turned off, and then sits for a while but not long enough fully cool down, it will start and idle fine immediately.
Last week I had the turbo off and after reinstalling it ran fine for a week or so.(although a did not drive a much in that week, there were 0 issues)
The problem arose after I decided I should rinse off the crossmember/exhaust area from spillage when I took the turbo off. I tried to be careful and used minimal water, but still managed to get water into the spark plug holes.
That was pretty much to be expected and I figured I'd just clean them out and it be fixed..nope stall
A few months ago I sprayed down the entire engine bay with cleaner/pressure washer with little to no regard for the electronics. I planned on cleaning out the plugs and drying everything off, but after minimal drying and without cleaning out the plug holes, it started and ran without issue. So I am puzzled how this careful and minimal use of a very low pressure hose managed to mess something up.
I did not start the car for a day or 2 after rinsing it and now I wonder if that may have been the cause of my current issue.
I'll check more connectors/hoses tomorrow. It really seems temperature related.
