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

Yes I found the problem this morning. It was a pin in the grey plug. I did not receive the termination caps with my swap. I have searched and searched on how to re wire the grey plug but found nothing. Finally I just looked at my gs300 harness and compared them. I saw two wires that needed moved to be the same as the gs300 plug. So I moved a red wire with blue stripe to get my e shift to work. This morning I moved a black wire with red stripe and it gave me the 12 voltz at my maf plug and o2 sensor! Finally got it. I do still have a bit of low idle but I'm sure it's a vacuum line somewhere. If you need a pic of how my grey plug looks I can send you one to compare.

Man that was a long time ago lol
So you don't know which connector came with your swap. Which doesn't really matter now. You can turn your key on and find the wire with 12 volts from that part and hard wire it to the harness connector or find the correct connector and install it to your cut wires

there are 6 wires 3black & red and 3red & blue. 1 black & red wire has 12v and so does 1 red & blue wire. Currently my maf sensor is getting about 5v or lower when the car is in run position

So the red and black wire with 12 volts needs to go to the maf. Find a schematic for the plug or if I remember right the wire was the same color from the body plug to the maf. Once you get that 12 volts to the maf it will line out and no more limp mode.

Lol I know what your going through man I was in the same spot. The other wire I moved in the connector was for the gear selector to work and light up so I could tell if it was in park, drive, reverse etc. I don't remember what color it was though.
