nope.
Wondering if I have to take off the manifold to change the check valve (shown in photos) on bank 1?
You live in Golden, CO not Anchorage, Alaska. It doesn't get that cold here. I live in Highlands Ranch and have been VTCS-less for 2 full winters now.
that is the solenoid which actuates the rod that the butterflies are on. You'll need to leave it connected to avoid a CEL.there is a green and white one way (check) valve that is on the bottom side of the mani. its connected with a vac. hose. not sure what its function is, but its a great spot for a leak when you go turbo. best part is not too many know about it and then cant figure out why they have a bad idle. leave it there until you are boosting a good amount. just like the pcv valve, it can only handle so much.

its not a valve, its the actuator for the VICS or VCTS. if you can get to it, you can replace it.
I think he is talking about this...
well you can't reach that without taking the upper off... obviously. So, is that the part in question? and... why do you want to replace it?
I think it is broken and contributing to my P0171 and P0660 error.
I am asking for advice about replacing it.
I hear a hissing sound coming from that area.
