How To Find A Vacuum Leak - EricTheCarGuy
Vacuum leaks are one of the biggest causes of engine performance problems.
This video is pretty straight forward in it's approach to finding a vacuum
leak. On thing I might mention is that not all vacuum leaks are at the
engine. Some HVAC systems run on engine vacuum and can cause a leak under
the dash in some cases. I've even seen vacuum operated door locks. Just be
sure to be careful spraying flammable stuff on a hot engine, you don't want
to take one problem and make it a whole lot worse. You can also use a spray
bottle with water to do this same test. It may not be as effective, but you
don't have to worry about spraying a flammable substance on a hot engine.
For more information on diagnosing engine performance issues, check out
this article I wrote.

1999 Dodge Ram 1500 all fixed. Here was the problem
I fixed the problem. It was the IAC (Idle Air Controller)
I'm sorry that the video is not more detailed but fixing it is not hard. A
few screws and a plug and some common sense on how it all comes apart and
is put back together.
I got a lot of emails and comments asking what the problem was so here is a
video pointing it out. I hope that it helps you.
