workingonit is on a distinguished road
cheap MAF runs as good as OEM, or maybe better???

Thanks, it's just my way.

I hope it does (but are you being facetious?). I think I'm getting positive results, already, on just two run cycles.

Being retired, on a fixed income (with mounting medical expenses for both myself and the wife, and unexpected septic tank repairs, etc. this past week), I would rather have bought another Siemens MAF, like my maybe original from 2001, for $216 at FCPEuro, but deferred it to later. I could've gotten it a bit cheaper at Amazon (or even a Hella @ $72 or Bremi @ $93, both from Rockauto), but those would've been just substitutes at higher prices for the cheaper one that Xchemist had already tried, with success.

I received the MAF in the mail this afternoon, and installed it, and ran two start/run cycles, observing g/s at various speeds, then compared test data from both (at idle) with another test taken months ago.

Not much difference shown, this early-on, but I felt the new MAF reached higher g/s from 1500rpms-WOT, though I failed to capture the proof on my equipment. It does show higher g/s at idle (though temperature differences may have affected the readings), and for the first time ever, the LTFT's fell by themselves (no action by me) while I watched my Foxwell. Perhaps more run cycles on the road will bring the fuel trims nearer normal? and I won't have to keep searching for vacuum leaks, ad infinitum.
