# 2 looks like the mass air flow sensor. I believe #1 is either the cam sensor or a ambient temp sensor. Is it screwed into the head?

I believe that is what #1 is in the picture. The MAF (mass air flow) sensor determines how much air is drawn into the intake. A MAP sensor (manifold absolute pressure) sensor is usually attached near the throttle body and has no need to detect air flow. Based on the picture, it looks like the MAF sensor. And yes, you would have a MAP sensor too.
