I'm still troubleshooting and when I saw someone said they had those codes and it ended up being the PAIR Valve i quickly blocked it off and my check engine light went off and the rig is running great at the moment. thanks for an alternative solution.
In search of new/ used working properly Pair Reed Valve - P/N 1735066010 - toyota shows this part as discontinued - does anyone have any guidance for me? I'm in CO with emissions testing. I currently have the system "blocked" off as i was getting codes 25 and 26 rich and lean.
