A couple weeks ago the car died a couple of times when coming to a stop which never happened before. I cleaned the IAC pintle and seat. Checked IAC counts at idle - was 30 which is high. Good news, high counts suggests no vacuum leaks but high counts at 650 rpm means the primary throttle blade opening at idle could be a tad too small which could explain stall when coming to a stop.
After finishing the idle setup yesterday, went for a drive today and drove perfectly - idle did not drop too low when taking my foot off the pedal and never died after an hour of driving and probably 2 dozen stops.
One more thing I will mention is that my original throttle stop screw measured 7.6mm extension from the mounting tab. I installed the new Hex head screw about 8mm extension (because I wanted more air through primary blade/less IAC counts) and this put me within a half-turn of my final adjustment.
