Have you logged at all? Even if it's not throwing a CEL, good datalogs might indicate the root cause. Especially if you can log the issue happening.


Odd as it sounds, verify the battery connections are good - clean and tight.


My first real guess is MAF sensor, possibly the idle control in the throttle body in need of a cleaning. I've had issues like this with a different car using MAP and of course that's barely similar, so these are wild guesses to get things rolling.


I had issues like this occasionally (especially from a dead stop) with my OFT tune on the '14... so it can be 100% tune related. I doubt that's your issue but note it just in case it makes someone think of something.
Hope it's an easy fix.
Oooh, good question. It does only happen when there is a sudden(ish) change in the throttle position. What does that indicate?

I'll ensure the battery terminal connections are clean and tight. I'll also clean the MAF. Those are quick, easy things to do. Thank you!
