O.k., I know I'm not the only one. I started the L a couple of weekes ago, after I started it I got a loud hum. So after it warmed up it went away. So I have been driving it now that the weather is better and it does it all the time now. It does not do it when I accelerate, but when I let off with no boost or any preesure on the gas pedel? I don't get it. I have not sent it in to have the intercooler redone yet. Could it be the SC?

Thanks guys,

 

Fan???? My Exploder, I mean Explorer, makes the same noise when there is no pressure, the fan kicks in at idle because that is when the engine heats up, no cool air running over it etc....anyways my ford makes that hum, if u hit the gas quick it will turn off, but it is rather annoying....dunno if its the same thing.
