I own a 99 I30 bought new, sticker build date on door is 2/99, never repaired, got a check engine light this week. I read the sticky in 4th gen. forum

My ecu looks different. by drivers right foot area
about the same size, but the screw hole had no blade slot-
rather: a round hole, and on the edge of it (trying to explain) a sticker. imagine a clock face-an arrow goes from 6 o past 9:00 to 12:00 labelled idle speed adjust. 6:00 is labelled low, 12:00 is labelled high,
from 12:00 to about 3:00 the line and arrow are dotted and are labelled "self diagnosis"
Inside the clock face between the center and about 4 ;00 is a very small phillips head screw.
Why is this idle speed thing not shown in the 4th gen sticky?
and will moving the screw screw up the idle speed?

Yeah 99s are different. The 'blade' screw in the earlier Maximas was replaced in '99 with a smaller white phillips screw. You need to use one of those smaller phillips screwdrivers to turn it. Everything else in that FAQ is the same.

how much is the rotation of the screw, stop to stop?

90 degrees? 180? 270?
