Sable 2000 With Dhoc Engine

My Sable 2000 With Dhoc Engine When I Drive I Hear Engine Sounds Like Grinding Mixy.... With Closed Windows. Though I Dont Feel Any Other Problem.
Recently I Drove 2000 Miles Trip And It Ran Fine.
When I Sit In Other Cars Like Accura, Saab Toyota...they Run Smooth And Quite Inside.
Is It Because Of The Fact The Dhoc Engine Genrates 200 Hp In Comparison To Regular Sable Giving 155 Hp As If A Heavy Engine Pulling A Light Body Car.
Does Any One Else Feel Like This Or Does My Car Needs Some Thing Taken Care Of Or It Is Normal?....
2. The Fog Lights Dont Run, I Have Never Seen Them Running Since I Bought It Used, What To Do.

I got it checked and was advised that the sound is coming from right passenger front wheel bearing , as such got replaced hub and bearing assembly and now it is running smooth....i think i should get a better milage now.

For fog lights to operate/turn on: PULL the twist light knob, while it's in the headlights ON position.

Thanks, it works but while pulling the knob it comes out....is it normal or i am missing some lock in it?

No, it shouldn't come out. The knob has had a recall or a factory bulletin on it, I'm not sure which.
