Wait did you find out the problem to your rough idel/ instant dying?
I have a 4cyl sonoma with exact same problem. I replaced so much stuff on it, I was told it sounds like a IAC sensor which may sound about right. But I just got done doing cylinder head. I have no clue what the problem is with this thing, but like you said it will die right away, and once its warm has virtually no problem. I thought origionally O2 sensor but that throws a engine code(which I dont have showing).
Post back on my 97 sonoma. With the solution to your starting problem.
Much appreciated man
