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.

I had an "engine lean bank 1 and 2" code and finally found why.





Misfire caused by a vacuum leak
Typical to an intake manifold gasket that is leaking, is an engine misfire, especially with the engine cold. In fact many cars will exhibit absolutely no misfires or idle speed roughness with the engine hot. Some may not even have lean condition trouble codes, in particular with speed density engines (no MAF sensor).
