That is correct. I might revisit this again soon but I just did a bunch of other work so I need to just get the car back up and running.

Did you flash the car? You can't just run a different sensor without rescaling maf... No codes should result from this unless you put in a bad sensor or a bad tune.

Yes, I reflashed the tune. My guess was a pin was not connected well.
I will most likely re-try sometime soon but no real hurry as of now.

Anyone have a part number for the plug that goes on to the harness or know where I can buy it?

Never mind, herenitnis if anyone else needs it.

I'll have to revisit this in the next month or two when I get my car out.
