Never can keep it straight because it seems backwards to me.

IAC not increasing the engine speed enough-
bad IAC, IAC connections,
RPM reading (reference pulse error)
MAP reading low vacuum making the mixture rich.
You ruled out - to high of fuel pressure.
Injectors to big for the engine or leaking.

Running rich makes a lot of sense because the exhaust smell is terrible.
IAC may be the issue. It works in that turning on AC or turning the steering wheel will adjust the idle when it drops. But the cold idle speed does appear to low. It is an aftermarket unit, the original has been replaced.
Injectors are rebuilt replacement units. I had one clog and cause a really lean condition. As far as I know they are the same size that was in it. They have been in there at least a couple of years now. I have not looked at the spray pattern since I replaced them so a leak is possible. Will look at that.
Don't have a good data log recorded, but that is not a problem to record it. I was going to do that today anyway.
