My Z developed a low idle problem last year when I put it up for the winter. I haven't gotten around to messing with it until recently. It doesn't matter if it's a cold startup or warm startup, the rpms will go to about 1k then immediately drop to 500 or lower and sometimes stall out if I'm not sitting there giving it throttle. I did some trouble shooting yesterday and pulled both of the connectors from the IAA, while the car was running, and there was no change. The connectors are pretty roached so they will be replaced first, but I wanted to see if there is anything that I am overlooking before shelling out the $250+ for a new IAA unit. Should I try adjusting the idle screw if the new connectors don't help? Thanks in advance.
