Well, after having everything redone on my ECU and making sure all connections are good it does the exact same thing. Any more input? I know it’s hard to diagnose something without having it in front of you so I appreciate any other input or advice you can give me.

My guess would be a vacuum leak at this point, but that is based on the old calibration and datalogs.
