Hey guys,

I'm going to try to be as descriptive as possible without sounding retarded with this question.

I stepped outa my Z, car running, no A/C on. And I can hear a popping noise every like 8-10 seconds. Very subtle, and probabaly wouldn't notice it normally. I went to the back ,and I can hear it in the exhaust slightly... but its definitely coming from up front.

The best way I can describe it is the noise is like popcorn popping..

I know this isn't informative at all, but I'm shooting for that rare occasion someone else had the issue...
