Default high idle....

For no apparent reason, my idle is 750 rather than 650. I didn't do anything, just randomly started doing it. I changed the battery, and it is still the same. does anyone know the idle relearn procedure for the C8?

Maybe it's in an OTA update? Did your software recently update?

Mine also has been sitting around 850 and I know it was always rock steady at 650. I'm taking it into the dealer this week to have them look at it, it was previously one of the symptoms when my cam magnets were bad and my timing was off although I'm not getting the surging or hesitation currently.

Also have what sounds like lifter noise in v4 mode so something is going on back there that isint right unfortunately.
