Hey so I did this and had the same results as you. I recently did an mpfi conversion, which requires taking off the upper intake manifold. Is it possible that when I reinstalled it, it didn’t seat properly on the lower intake manifold? These codes only started since doing that conversion. Thanks!
Thanks so much, I’m going to go try this method
