Now that it's nice out and I have the windows open, I noticed a sounds from my engine when I accelerate that sounds kind of liek a baseball card in the spokes of a bike. It's not crazy loud, and in fact I have to turn off the radio and listen for it. I can't hear it if I accelerate hard b/c all I hear is supercharger whine. Obviously I can hear more sounds from the engine now that I have the CAI on, but I was wondering if this is a sound to be worried about. The car runs fine, but I do notice a rough idle sometimes (not even often or consistently) when I just start it up and it is hot. The two don't seem to be related on the surface, but I thought I'd mention the idle just incase.

Thanks!

 

I noticed more sounds with my CAI on...but I don't think it is anything to worry about. I have noticed a rough idle too when it is warm...I haven't figured it out yet either.

 

with my cai on it sounds like a belt is rubbin but in know it is not...just make sure u dont havea anything in the fans and such

 

Good Call Jeremy.
