2004 Chrysler concorde quesitions!?

[C F]

My car squeaks when im driving and when i make turns. What could it be? Sometimes, when im waiting at a red light my car will act like its about to kill but never does? Could that be spark plugs need to be changed?

Thanks
I bought car in 06 never change spark plugs....

Loose power steering pump belt. Probably means the tensioner pully is bad. That belt also runs other stuff, including the water pump, so check it out.
