I'm dealing with this right now on a 26 year old vehicle! Most vacuum hoses are original and fixing to replace every last one! Tired of poor gas mileage and power. New hoses soon!

My car seems to run fine. No check engine light. When bringing my car in for service, two different shops mentioned I had a vacuum leak. Does this make sense?

I replaced my fuel pressure regulator and valve cover gaskets and back radiator, heater hose then my iac p, 505 came oni checked all vacuum hoses 3.3 vg frontier, could a leaking vertical heating hose in the back of the manifold cause it to suck air in even if it has anti freeze running thru it set off the iac code, never had it till I took of the plenum left it upside down over nite for rtv to dry I'm stumped I think the heater coolant hose is sucking air into the manifold, do they work together

Drive a g37x and believe I have a bad vacuum leak for a couple months now. wondering, if I buy new intakes system and get it installed will it fix the leak no matter where it’s coming from or does the leak have to specifically be found first.

Great video but it feels like I’m reading a high school student paper trying to reach a word count 🙄🙄

Nice video, but
Showing too fast, instead showing where could be the possible leaks.
Step by step hoses and main fold and other parts

Constructive criticism: lose the background noise!
The subject & your narration of it is great. The addition of distracting, monotonous & annoying music ruined the vid for me.
