CGT stalling when cold, I'm baffled

[David Mueller]

Along with the wiring check suggested to you ( which you have started it
appears), any vacuum leaks ( loose hose clamps or small cracks )or dangling
vacuum conncectors that are hard to see ( like under the ISV )?  I did some
work and did not see for a long time that a small vacuum connection had come
loose.   When my car warmed up it was not as bad but still rough idle.

Any ways for what it may be worth.
