I checked the ecm voltage to the maf sensor and got 5.01 volts.
I checked the resistor on the car with my spares and they were spot on.
So I returned the maf wiring to stock.
Ran another scan and the maf (P0100) trouble code is now gone.
But I still have the egr (P0400) trouble code. I know the egr transducer is bad so putting that on won't work. I ordered a replacement but it hasn't arrived yet.
Not sure why the maf and egr fixes didn't work. Was very disappointed to find that out.
I'll update when I get the replacement transducer.
I'll report how the maf affected performance later.
