I feel like a 25-50 rpm increase in base idle would be enough to stop the low idle stumble. Maybe worth easing it up a 1/2 turn or so on the stop screw to see.
Thing is with this cable running the rpm up when connected I cannot know what the iac counts are at normal idle speed. It has been displaying 38 counts at 1,000 rpm.
I'm not sure on the 02 brand. It's either AC or Bosch. I may still have the receipt. I don't buy the cheaper parts but that don't mean much these days.
Yes the stumble happens when fully warmed when I am stopped in traffic. It idles good for a few minutes then starts to slow down and feel like it will die. I tap the throttle and it picks back up but will do the same thing again. Sometimes I move it to neutral if I will be in a line for more than a few minutes.
