Does this year Vibe have electronically controlled gas pedal/engine link to "smooth out" driver input?

Same here. It is very low level but a definite "zip" whine. Could it be somehthing electrical adjusting to the throttle being lifted? Car runs fine.

I have a 2006. I am hearing a noise--a short burst that sounds like a motorcycle accelerating very fast or like a quick "turbine" sound--a zip like sound--when I lift off the gas pedal. Car seems to run fine. Gas mileage good. Just had oil changed. Any insight into this?
