DanielWillis Posted August 31, 2015 Posted August 31, 2015 Hi guys, Apologies if this is a duplicate post, I know a lot of people have posted about chattering noise but my case seems a little different to the usual idle noise. I have an '06 350Z Roadster which is completely stock (for now ), just hit 50k miles. It seems to have developed a chattering noise which happens in the following situations: - While revs drop during a gear change - Under acceleration in 2nd, 3rd, 4th and 5th up until around 2500rpm - When revs are hovering in 2nd, 3rd, 4th and 5th It can get quite loud and living in Edinburgh City Centre can draw slightly more attention to the car than I want! Any thoughts? Thanks in advance! Quote
ZMANALEX Posted August 31, 2015 Posted August 31, 2015 How do you know that it is stock ? have you owned the car from new? If SMF fitted. then that is your cause. Otherwise if definitely stock, then could be DMF, exhaust baffle, exhaust rear box heat shield, cat heat shields, however could be many, many other things as not enough information provided. If you are up in Perth at any time, then just swing by and I will soon tell you what it is and also the fix. Alex. 1 Quote
