Very Strange Noise.. HELP!

[markdoddridge]

I have an 04 H2, and the engine is making the worlds strangest noise. Its not a ticking, or a rapping, its like something got loose and is bouncing around inside the engine compartment.

Its only present at idle and slow speeds. Once i speed up it goes away. Also when i rev the engine it doesnt get louder. Its almost like a screw or a bolt fell out and is rattling around somewhere.

If anyone has ever had a quarter get loose inside their dryer, it sounds almost exactly like that, but faster

Anyone had anything similar to this? the check engine light is also on

best bet would to get the truck scanned and see what the code is that's beging thrown.

O-reilly or auto zone will scan it for free, not sure if the dealer charges anything or not. I know auto zone will even give you a small receipt printout of all the codes.

thats odd...First place I'd start looking is around the fan shroud. But your check engine light and only hearing it at low rpm I'd be looking at the valve train also.

W/ the truck in park at idle or low rpm, does it still make the noise?

Yes, at idle in park and at low rpm it makes the noise, hopfully its not something terible wrong. I had no idea autozone would scan it for free, im definatley gonna do that.

What do i do with the code once i get it?
