Corroded PCM
This is what winter driving where they salt does to your PCM.
I'm sure this was accomplished by never cleaning the udders, parking outside, the dumb placement of the PCM etc.
Happy to say after disassembling the housing, the corrosion didn't make it to the inside. The connectors and pins were ok as well. Kudos to the designer of the housing!
I have been chasing gremlins, so once I saw the corrosion, had to take it out.
I believe I will replace with a later PCM anyway.
Just thought this might interest some of you.

It's all quite nice now.
I don't drive it in the rain or in the winter.

I have this all back together and running.
And need to say I was wrong about the PCM location. It's right under the batt.
But nothing else was corroded. So I still think it was salt vs alum damage.
I orig took all this apart chasing a TPS error issue which causes the car to go into reduced eng Pwr. I wanted to look inside the TAC module and check it's connectors. Connectors clean, and the TAC is glued inside a plastic box. No way I could see to look inside w/I destroying it.
I guess just keep driving and see if the prob returns. Sucks not being able to trust my car
