How to replace intake manifold gaskets on a4.6L DOHC engine

Tester, iam sorry it said , p2004 , i beleave that’s stuck open bank#1 !
And I out the the part from my other Mark base on it , it had one place for
vacuum line and three wires and I just took the one from the base and with
it hooked up I took the vacuum hose off and pushed it closed and put my
finger over it, while holding it closed and let go of it and it was holding
vacuum, and it held it open! So I guess it’s working I don’t know it’s
driving me nuts! Thanks George from st louis

Thanks brother I didn’t know!
