Thank you! Mine just started doing it, the diagnostic isn't registering anything. I'm just going to drive it until it actually stalls out or kicks a code. I was thinking vacuum leak, idk, I sea foamed the gas tank hoping that would help. Over time we'll see I suppose, hopefully nothing major. And I had the alternator replaced.

Update;
It was an idle relearn procedure that was needed, 4 fuses needed to be removed for one minute and returned.

My car is running great now!
I think I wrote this on the wrong forum though, I have a 2011 Scion xb manual.
