Squeaking noise while driving off with little gas

[yarisftw]

Hi guys, when I'm driving off my Yaris and releasing the clutch, I normally give very little or even no gas. Previously, there were no issues with this, but recently my Yaris has started to make a squeaking sound during drive off, almost like metal rubbing. If I give it enough gas, the squeaking will disappear. I am not sure what is going on.

Hi, 

this can be as a result of loose heat shielding along the exhaust pipes or broken exhaust pipe brackets. Driving off the line with low rpm will cause engine load and vibrations which can trigger those metallic squeaks , another reason can be a worn out clutch.
