Hey there hopefully someone can help!!
I installed a used jb4 this weekend. I started the car and had a rough idle i checked codes and had both 2abc and 3100 removed jb4 and everything works fine. Could it be a bad jb4 board? Car starts up good then goes into limp mode with both codes. All pins are straight and look good. Thanks!!

Yes, I'd say you are right. A bad or hacked flash?

Anyway, return it if you can.
