It's now running in speed density mode. Removing the ground killed the MAF. You likely need a new one, or the old one just needs a good cleaning.

When it comes to sensors and such, you should always use either genuine GM or other KNOWN good brands. Unless you KNOW the quality of the sensor, I would shy away from eBay.
