I have a 08 Z71 tahoe ,1000 mile, with it I don't have a problem.
but I am wondering about strange sound that came if I start the car and move it just after I start it (it came when rbm below 2000) it come from under hood
and I knew the sound since I bought the car. I was told it came from the air filter.
any idea {thanks}

Welcome to the forum.

Need a better description of what the noise sounds like. Is it still under warranty?

It isn't a loud sound,{u cannot hear anything if u r out the car),
and I think if there any passenger and ask them if they can hear it .
they can't .

If it doesn't happen 'til you move the truck, then it's not the air cleaner. Could be brake pads sticking to the rotors due to moisture. If it's done it since new, should take to dealer.
