Vacuum noise when idling.
I was watching someone park my car and i heard the engine make a vacuum like noise. Anyone know what it is. It lasts for like 5 seconds only. We got a mechanic to check the car before we bought it 1k km ago a month

Many cars have air injection pumps that kick in on cold starts for a few seconds (all for emissions). I dont actually know if the IS models are equipped with this (im sure someone can confirm this here) but i think the GX, and most of the 4.7/5.7 Toyota V8s had the injection pumps. They commonly failed on the Tundras.
