I am getting a twittering (squealing, chatter) noise under acceleration. As soon as I let off the gas the noise goes away. Happens whether in park or drive.

there are so many things that can make unusual noises on cars that you will need to give more information for some kind diagnosis to be made. Noises are terrible because I need to hear the noise and listen to where it seems to be coming from. And, that's when it's right in front of me.

Is it coming from a belt or tensioner? Is it from an idler pulley or maybe the alternator? Is worse when the engine is cold or warm? Could it be the exhaust is plugged up and air is escaping under pressure? Is it pre-ignition?

if you slowly raise the engine speed, what rpm does the noise start? Does it keep getting worse as you raise the rpm?

Have some one use the gas pedal and have it make the noise while you are looking at the engine with the hood open. Can you localize the area it seems to be coming from? Is it coming from underneath by the exhaust?

so many things...
