I installed my edge with attitude the other day. when the truck is cold and I start it there is a faint pining sound. When it warms up it go's away. any ideas?

 

Peranoid? I remember when I installed mine I was so paranoid of every little sound the truck made that I almost removed it. Now I just drive and watch the guages and not worry about it. Ohh yeah check your oil and make sure your truck isnt "making" any extra.
