This...do a throttle relearn.

I read on the forums of issues with the vipers if you adjust the driver demand tables too much off what they actually are it goes into limp mode and runs really rough? I want to say.. I would look up that thread on here.

It does indeed.

how do I perform throttle relearn?

VCM scanner special functions

Also have experienced an issue between plastic or aluminum throttle bodies on those Gen 5 Vipers. One being less reliable than the other, prone to glitches and going into limp. I forget which it's been a while. Maybe someone else can say which version is best. They're both genuine Mopar items.
