How do you clear a stuck open valve?

 

Is an intake valve? Did you get a code?

One of mine stuck open last winter. I just sprayed some seafoam into the back of my intake manifold and let it sit overnight. When I started it up the next day, the valve was able to open and shut again and the code has not come back since.

 

Might be nice to know which valve?
Do a search as there are plenty of good threads on sticking SSV and the like.
Depends on which valve it is!
