[V8] FW: Emailing: 006977

That's what I did.  These codes are new.  Likely the speed sensor code
is not real; just the knock sensor code and brake light code, plus
perhaps the ISV.  
I always try to do them in order, too.

There are a lot of codes so you should do as one wise man once said
"clear the codes and see which ones reappears".

BTW the wise man was Keith aka DasWolfen
