Hey guys,
So I’ve always wondered about this, and I’m not sure I’m asking google and searching the right question…
My question is - Why does RPM change at idle. Let me expand on that.
So I get why AC affects RPM - You’ll have a much lower RPM with no AC than with AC.
But for instance, I live in FL - it seems that weather affects the RPM range at idle as well?
Some days at idle, with AC on - I’m between 800-837 and other days I’m 865-880 (something like that)
Why is this?
Why I ask - is because it makes quite a different in idle volume in the cab
Thanks.
