I have read all posts regarding this issue. Most seemed to have replaced the electric valve body plate and cleared the code and they are good to go.
Now, I also get the P0173 and P0170 for the fuel trim, i.e. MAF, so most people say.
Would it be advisable to do the MAF first, then see if that helps?
I am far from a dealer and I have cleared CEL codes with the Advanced auto parts generic scanner. Will this get me out of limp mode?

As well, if the consensus is the plate, can someone point me to the part and directions on where this piece is, any pics would be great as well.

Thanks!,
Chris
