For about a month now i have been hearing a pritty loud squeek noise when letting off the gas, it does not happen unless i get on the gas a little or punch it, iv noticed it a lot at about 4000 rpm, again.. it happens when i let OFF the gas. im thinking a spring or something? when the front end falls down after the torque...? anyone hear anything of this? somebody suggested the throttle body? please help
