If you get 1.9v at idle that is correct though which means you are getting voltage to the MAF.
You have a wiring problem.
Did you try disconnecting the tach per AristoJ's recommendation?

I was getting like .89 volts at the maf before I moved that wire in my grey plug. Once I moved the black wire with red stripe to the correct spot I saw 11.89 volts and all was fixed. My o2 sensor and maf had the correct voltage.

The ECU might send 12 volts to the MAF but this is only with it unplugged (previous post on other page)
The MAF will ONLY read up to 5 volts when plugged in and when operating because it is a voltage reference between the ECU/Hot Wire/Thermister (voltage reference is VB+ usually denoted for those for read schematics or are into electronics) and virtually ALL car manufacturers operate this way
So because he was measuring the MAF plugged in and was getting the correct 1.9V at idle he IS getting the correct voltage to it
Again, there is another problem and it probably has to do with a spliced wire/connecter etc.
That aside, the grey pin I pictured is the correct way, it should not be moved and that might be why you're having problems your self with the shifter. The picture I used was from a perfectly executed swap by a member on here

Yes again you can check for 9 to 12v with the plug DISconnected but once connected it will only read 1.9v idle, 2.5v cruising, 3.7v WOT etc.
So AristoJ had a different plug. But Kenny has the correct plug and should leave it alone. You just gotta figure out why you're in limp mode man. Triple check your wiring and some more 2JZ swap threads

when I turned on my ignition, tested the pin in the maf plug and I got 11.7 volts or so when I had re pined the maf plug and moved the black wire with red stripe.
Before i moved the black wire with red stripe in the grey plug I would get .89 volts and so like you are now. I say move it, turn ignition on, check the maf plug for more voltage , worth a shot
