After installing a rebuild ecu I am still getting this code, the Snap On scanner i used says 00212 Undefined ?

Anyone every got this before?

I am thinking the Power Transistor is causing my problems. Car runs great from a cold start. Once it is up to temp and I shut it off, when i restart it seem to be only running on 3 cylinders with a bad miss.

But if I don't shut it off it will run fine all day!

What do you guys think?
