    Idle going up and down when first cold start of the day....

    Not sure if it did it before or not, but my L83 seems to rev up and down a couple times when first started in the morning, more noticeable when colder out. Doesnt seem to matter if Im running E85 or not. So I dont think its that. Is this normal? I tried searching the forum, as I remember someone saying something about a few idle settings that couldnt be changed with HP. I will get a log on here today after it sets again. thanks in advance.
