Sure, you give it throttle and it cleans it up, 1500-2000 rpm probably.

Something killing spark to one hole, temporarily? New wires, new plugs dont help.
Didn't sound like a dead hole. And I'd think you'd feel it. Especially if you shift into drive.
Hate to say it but it really sounds like the '80s carbureted engines. It was a real bear to get them to idle right.
Just thinking about this, is your EGR valve connected?
It is. I've checked it for leaks too. What are you thinking? Remember, its still only for those 30-40 seconds. ;)
Sure... EGR slightly open can cause problems. When ecm is warmed up it can cover for many small issues. It's not likely to be EGR but I'm just covering all the bases.
30-40 seconds, sure, but still needs six degrees extra timing, too.
I've carb cleaned everything looking for leaks. It doesnt per se "need" it, it just likes it better, its more free. Like any small block Chevy I have ever dealt with.
Heres pix. Mind you, the box was changed as a test.
Hopefully the number you want is there. I googled those numbers but come up with nothing....hmmmm.
