Small vacuum leak V6 Auto 4WD SR5

[joeyz]

Has anyone had experience in finding a small vacuum leak that is detected at the Emissions Center or a repair shop, but doesn't activate the Engine light? I have a 2005 4runner V6, Auto, 4WD SR5?

Is your idle a little higher than normal due to this?

If it's a vacuum leak use carb cleaner to find the leak. If it's a evap leak use fog!

How did they determine it's a vacuum leak?
