@ 250k I guess the valve tronic could be getting sluggish, but with the codes you have it wouldn't be my first salvo in the parts cannon.

It’s all good man you gave me the inspiration I needed to replace it anyway. It was going to go bad at some point who knows maybe even this winter.
After the full system reset, and resetting all of the modules, that O2 sensor code came back as pending. There’s definitely something going on there I need to go look at the O2 sensor tomorrow. I read that a bad O2 sensor could cause shuttering and shaking during acceleration. I hope that’s what’s up!
