Still giving it a little time to see if the battery was the issue, talking to all the OEM testing calibration guys at work we all would not fully see why there would be an association between ethanol number, low battery voltage, and a wheel speed sensor in the most logical reason. Battery was at least 4 years old, and I had battery issues 2 months ago (similar to when the issues arrived) and it went away so I concluded bad connections or something like that. Car does seem to crank less on startups now, should be a very similar CCA.
I had not fully heard of the weird things low battery numbers can do until I talked to the friend who helped me install it talking about the issues he had with a bad battery on his Cobalt a few years ago. Let's hope I can at least retain ABS haha

So on the Harrop, the evap purge valve is transferred from the bottom side of the stock intake manifold, onto the underside of the supercharger. Is this the same for the TRD? Did you make sure to connect the hoses properly and have you checked it to make sure it's still connected electrically?
