Am i suppose to smell exhaust fumes coming from the engine bay, specifically the header/heatshield area when revving the engine? I smell strong exhaust fumes when doing this... I also notice that ive always got some black residue on the top of the under side of the hood... prolly from the exhaust fumes.

Also, how do i change the power steering fluid? Does it need to be Flushed ? or just drained and filled? If so, how do i do this? And what fluid do i need to buy.

thanks
Sean

I have also noticed that the cat or something under the middle of the car, is vibrating on/off at idle... which it is noticeable when standing to the side of the car. It didnt use to do this.
