P2119 code
 

I usually only run e85 but the delivery got delayed/late so i put 93 in and my car got mad and threw a p2119 code. Im positive its not tune related because my man zach at CSG did his blessings. I got it straight i just checked the throttle-body reconnected and cleared codes no more codes so far but just curious anything weird like that ever happened to you when doing a sudden switchover to octane

Did your car hit limp mode or anything? Or was it functioning normally when the code came up?

Limp mode it struggled bad and cut off twice while driving before i pulled over

You running flex fuel or did you flash to another tune? If you reflashed, what procedure did you go through before reflashing and how much e85 was in the tank when you refilled?

I would think it should have nothing to do with switching over fuels when you're on a flex kit. Could be that the TB just had a hiccup. But I would think if that was the case, it could be faulty and may happen again in the future.
