Has anyone else ever had a weird sound on their truck that seems to go away as you drive. It sounds like a old truck when its cold and when I step on the gas. As the truck heats up it goes away. Anyone know what I'm talking about. I have the 4.7 btw. Thanks

 

same here lol. know exactly what your talkin about but once its warm its fine. and it has to sit awhile for it to happen

 

but do you know what causes it?

 

What year? How many miles? Perhaps an oil problem? Could be an exhaust leak.

 

its an 04, 43894 miles. I don't know about an exhaust leak because it goes away when the truck is warm.

 

its prolly ur blower
