I’ve been fighting a P0441 issue for forever. I’d like to see pictures of the vacuum rail on top of engine to see if I have the hoses correct from the vsv if anyone would post!

I still can’t quite see the far left vsv piping. I think I have it right but not sure. It cranks hard and when I switch them, it cranks fine

 

That probably means the VSV has a vent on it so if the lines are reversed then it creates a vacuum leak. I'd leave it and see if a code gets tripped if not you have it correct.

 

I guess ill I’ll go buy one of those vape sticks and look for vacuum leaks also but it’s intermittent. The longer it sits, the harder it cranks sometimes but it always fires right up after driving then stopping briefly and restarting.
