That code is a low frequency code for the mass airflow sensor. Did you replace the MAF with a Genuine GM part? If you used an aftermarket MAF sensor, it’s probably junk, and I would recommend spending the money for the GM part. The hesitation can be many different things, and it looks like you’ve changed quite a few parts! Could be injectors or lack of flow, but if that MAF is still setting a code that can do it too.
