Crazy Space ship noise in warm weather start ups
My car *in sig* has about 101,xxx miles on it and i've tried to describe the noise i'm hearing to GM but they didn't know what I was talking about. Here it goes, when I start up my car in warm weather after it sits for a bit I hear a weird noise that sounds similar to well.... I guess a supercharger or a space ship stuck in my exhaust . My car has been making this noise religiously in warm weather not cold and it really only does it at idle but you can hear it for a while if I don't rev it up. If I rev it up the noise goes away until I get back to idle while in park or drive when the car is still warming up. The car will also make the noise if it's still warm too soooo it's a bit embarrassing. I have replaced the serpentine belt and got rid of an annoying belt squeak but the "space ship" noise is still there. I can hear the noise Very well in the engine bay if I put my ear near the manifold, coil packs and I can hear it out of the exhaust.I don't seem to be losing power when the noise occurs.
Help?
