The Dreaded P0102 MAF "Mass or Volume Air Flow Circuit Low Input"

[J57ltr]

It makes a lot of sense you have a poor connection into a splice or where it's supposed to ground. I don't see an issue with grounding it directly, but just do it temporarily then find the root cause or you may have other issues related to that ground and whatever else may be tied into it.

Thanks Jeff, that was the logic in my thinking. If you look at the MAF, the thing has a BIG + and - (plus and minus) sign molded into it! So that made me think both should be at "true" BAT voltage, and why would anything be spliced into a "Labeled Ground" (in series) that would impart impedance? I Know GM does some DUMB S***, but that would take the cake!
