So the other day i started hearing this clunking noise, I know its not knocking, It only does it at idle. goes away when you hit the gas. Doesnt sound like the catalytic converter rattling. It sounds like its comming off the power steering pump or somewhere around there, This is on a V6 3.8 i posted here to get more feedback. anybody have any ideas. COuld it be the power steering pump this fluid is pretty dark
