How to check IACV and Vacuum lines
Whats a good way to check if my IACV is failing. Also what is a good way to check for vacuum leaks. I remember something about spraying brake cleaner or carb cleaner on vacuum lines and when the solvent hits a leaky line the engine will idle faster, something like that. Is this true?
