Box O Rocks
My motor sounds likes it has rocks in it on light throttle application after accelerating. By that I mean it does not make this noise during normal to hard acceleration, only during the time I feather it to shift or hold it at current rpm with light load. It is worse when the engine is cold. The car has 29K miles on it and is a DD. It still pulls strong and idles perfectly with no knocking.
Any ideas?
Is it common?
Timing chain?
Clutch rattle?
TIA

It's an 05. Thanks for the inputs. I may have to take it in and have it checked. I have the GMPP on it so hopefully whatever the problem is they cover it. It was a GM certified car when I bought it in July with 20K on it. Based on my experience so far I personally I don't think that means they did anything more than wash it, clean the interior, and add some tire shine.
