I have tried to search so dont tell me to search. I have also taken my car to the dealership and they sprayed it down with water and said if it starts doing it again then just spay it down. I really really dont want to grab a hose from my front yard and just start spraying my engine!!! So now ill explain the story when my car sits at idol it will stat to squeak sounds like the belts or something. BUt then when i barly giv it gas like rev it 500 RPM the squeak goes away. Also when i shut my car off it like sputter squeaks! what is wrong with the 350!??

 

proably the belts...

Check the tension they might be too loose or too tight.
