Default Manifold Removal

Anyone know if I can get a manifold off without taking all the eltronics off of it? I just need to reconnect the maf sensor which I am pretty sure popped off. I don't want to disconnect anything I don't have too. I just need to slide it up some.

you should be able to reach the back of the intake manifold to get to the MAP sensor i'm pretty sure.

Taking it off isn't a problem just seems like a ton of work I really don't want to do to check on a sensor.

Okay, I have the manifold moved to check the map sensor and it looks fine. To double check though, The map sensor is the one located on the back of the manifold correct. It attaches directly to the back of it? That looks fine but I keep getting code P0107. Anyway, it gets worse, something else broke back there and I don't know what it is. It stands straight up and has a one pine sensor in it. So I am going to completely remove the manifold which I really didn't want to do cause I didn't purge the fuel line. Anyone have any idea what that is? It sits right behind the manifold and goes into the top of the block in the back. One pin sensor, it is a cyclinder that goes straight up and down.

Its your oil sending unit. Alot of people break these when pulling the manifold forward. You have to be very careful and lift up and you pull forward to get over the sensor, and what do you mean purging the fuel lines? when you remove the manifold you don't have to purge the fuel lines or anything like that you just have to pop of the fuel rail and leave all the fuel lines hooked up.
