Help!
I have a check engine light with codes P0205, P1005, P1004, P0305.
I have replace the intake manifold valves, both the long flapper in back and short nub in the front

I am still getting codes.

I think I need the Intake Manifold - Mopar # 4593649AD. I can not find one. All sites say unavailable or discontinued.

Any ideas? Can I take my existing off and clean???
