Hello,
I have a 2016 Chevrolet Colorado 2.8 Duramax with a serious issue.
I have the countdown process and it will reduce the speed to 4 MPH shortly due to the "exhaust Fluid Quality Poor". I found a P20EE code, I bought a new MPVI2 but I don't know how to use it in order to fix that issue. I would like to delete the PDF and do whatever is useful to have my truck back on the street.
I appreciate any help in this.
Thanks
