Hopefully you guys can help me out with this. I have an 05 4.4 w/ 51k.

When the temp is cold outside, I'm talking about 60 or less, I get a loud squeaking engine noise at idle. When I press the gas and the rpms go up, the noise goes away. As soon as I take my foot off the gas and the engine comes back down to idle, I get the squeaking noise. I have attached the thread that deals with this in the 3.0 engine and it seams to be the intake runners but no one has addressed this on the 4.4 and I'm not sure if that part is on the 8 cyl engine. Can anyone advise me as to what is causing the noise on the 4.4. I have included the link for reference for the 3.0 engine.

thanks to all who answer.
