son of a biscotti... I typed this long-ass response and it didn't post. I hate that.

To me it sounds like a controls problem rather than a problem with hardware (excluding wire connections and sensors).

You didn't say whether or not the car is warmed up, or if that matters, so I'll assume that the behavior is the same hot or cold.

You've recently cleaned the injectors, so potentially they're flowing better than they were before. If they were flowing especially poorly before, then the long-term injector trim would likely be a fairly high value. I would expect that the short-term injector trim would be adjusted to compensate (assuming closed-loop operation) and you'd see no problem.

I'd start by looking at the IAC valve and the circuit that controls it, to make sure that the inputs and responses are correct.

dunno... post the solution when you find it, I'm interested to hear what it is.
