There are no more electric chokes, fuel injection has done away with them. So it is either a slipping serpentine belt or you have a symptom of a alternator problem.

If u dont think it a belt go to harbor freight and buy a mechanics stethascope. Real carefully put tip where u hear sound coming from to locate where its coming from. Clean scope and take bac. U can also use a long screw driver and tip to probe and ear on handle to listen. Jus more awkward.
