I havent done the pcv hose, it seems like it would be difficult? Its a metal hose isnt it. How do u go about changing it out?

And yes I did the fuel filter, fuel pump tonight, ( car seems to feel a little better all the time, but still has a f'd up idel after I drive it around a bit. I have noticed a whistling coming from the engine compartment somewhere, does this indicate a vacuum leak?

I bought a code puller, and I dont get any codes!
Thanks for all the help
