help! please.

EGR valve? bare with me here im 18 and me and my dad arent the most mechanical guys in the world. We are learning slowly but surely. Where is it located? what does it do? how do i check if its stuck or not?

The EGR valve is right between the dipstick and the heat riser hose in the 3rd picture and has a vacuum hose running up to the radiator. It allows exhaust gas to enter the intake manifold and cause your engine to stall out instead of idle. It's a lot cheaper to get 2 new EGR gaskets and sandwich a block off plate between the valve and the intake manifold. That will also allow you to get rid of the 2 vacuum hoses that run to the radiator and eliminate 2 potential vacuum leaks.
