It's because your accelerating very slowly. Your cars a automatic right. That weird sound is probably the AFM kicking in . AFM is the 4cyl mode the auto SS goes into under light acceleration to save gas. If your easy on the gas petal it will kick in around 25 mph with a slight vibration and a slighty different exhaust tone. It will turn off and the noise will go away if you accelerate a lil faster...

If this happens hit the gas slightly harder and it will go away. You can play with the accelerator at all speeds and you'll notice this happen. Or hit cruise control at 65 mph and you'll notice it as well, not as noticeable as the first method but if u listen carefully you'll hear it.

Hope this helps as far as you axuli gauges goes take it back to the dealer. That's why we got a warranty.

I had the same problem.... I went to Jannetty racing and purchased an (SCT) tuner and had them make an "AFM DELETE" only tune for me and WHAMMO NO more vibration. It was even worse when I put the exhaust on it!

Another GM failure.... The AFM which you're not supposed to feel when it changes. They failed miserably on mine... I felt it all the time! Vibration and bogging down sensation!

I feel something similar when im at a constant low RPM speed.. i think this is the AFM kicking in as some of the other posters have stated.
