  • IAC reading when off idle.

    Finally got the car out for a drive and after a while brought up the software on my phone. I noticed that the IAC had a higher percentage (16-17) versus the 9 that I have at idle when fully warmed up. I thought that once the car came up off idle the IAC would drop down to zero until it was needed for idle stabilization. Anyone have any info on this. It may be a normal thing but certainly not what I expected.

    Normal ...Dont be alarmed, Iam sure the engine was running great, like before.
    Don't get too caught up in the numbers.
    Just give the Engine what it wants &
    Let the numbers be what they are.

      i drove mine today to work for the first time and the iac was in the 25 to 30 range. but you have to know the iac will adjust up and down as needed so i would not sweat it. mine ran great so i won't get caught up in the numbers
