Wow thanks to y'all for this thread. Was exactly my issue from those codes. Had to go through taking off the intake manifold to see the part & replace it; what a terrible place to put the part.
Car is a champ again.
Saved $500 labor.
I ended up not bolting the part to the engine, and left it more outward so as to have easier access next time in case it breaks again; no need to take off the intake manifold again.
