rattle is driving me nuts

[evillecutter]

thanks everyone it was the heat shield - but also wondering if anyone has ever had a rough sound coming from your a/c compressor? sounds gets different and lessens when a/c is turned on

It could be the clutch on the A/C compressor. Have you tried to isolate the sound to the compressor? I used a long (24") socket extension jammed in my ear and set it on different (non-moving) components until I decided that the serpentine belt tensioner bearings were shot. Replaced the tensioner and idler and all is well.
