6E Question - IDLE SPEED TIME OUT IAC STEPS vs COOLANT or MAT
Does anybody know what the table does?? is it when a set target idle speed times out and the IAC needs a starting point for a new idle speed vs temp??
and looking at the ARAP hac there's 2 columns for IAC steps in the table... any idea why there are 2??
