I think its time for new belts. Look at them check if they have any stress or cracks in them
As for the hissing sound umm Is the intake system on you car stock?...
Check hoses for any leaks

yea..... check your belt. They might be ready to be replaced. If its not that check the tension. It could be they are just loose, or if your lazy spray some ****ttttt over it and hope it disappears

The hiss could be a rattle in your colector or heat sheld. I had a bad rattle from both. At 2000, 2500, and 3500 but know other time. knocked of heat sheld. Welded metel around colector got rid of most of it. I think I have to get a header to get rid of it all.
