88 Turbo II won't idle past 2k

My T2 decided today not to rev past 2k. I've been running a base tune on my PFC for the last 1300 miles to break in my motor. I am thinking perhaps it might be that the TPS is crapping out but wanted to see if some adjustments can be made on the commander that might help this issue.

Make sure both TPS voltages are the same if using stock throttle body and TPS.
Make sure the map sensor voltage is working and getting to the PFC.
Lastly is the crank angle sensors working.

I'll check the voltages on the MAP and TPS. The CAS is timed correctly. It sucks since I can't drive the car with the intermittent issue. It's just weird since it happened out of nowhere.

Here is a weird action that has actually worked for a few over the years.
(1) You need to either have a backup of your current map or make one.
If you have to make one first, you have not been a careful tuner, after backing up, edit the complete map with the DL software to insure it being accurate/correct looking.
(2) Initialize the PFC map to reset it to original values.
(3) Reload your map back into the PFC.
(4) Start and rive the car again.

Some PFCs have had errors introduced by unseen forces, maybe cause by lightening or gremlins.

Just post up screen shots of the sensor switch screen and monitor screen, without at least that data every response is a guess.

I have adjusted the VTA2 to around 1.18V on idle but it's still cutting out at around 2k. I have also replaced the TPS with a new one I purchased from Mazda and it hasn't fixed the issue.

You did not follow the instructions and connect the FRT to 3F

Everything is connected as the instructions said. It ran fine for 1300 miles.

Disconnect FRT from 3F and redo it, if they were connected, VTA1 & VTA2 would be reading the same.

Would you recommend soldering the wires this time?
