My supercharger started to rattle at an idle and I know that its a common symptom for the coupler going out. I already had a new one so I put it in and I still have a rattle noise at idle. I pulled the sc belt and started it just to make sure thats where it was comming from and it was quiet I also checked the idler and tensioner pully. It sounds like the noise is comming from the snout but when I had it apart I couldnt feal any slop in it. Any ideas on what I should do next? The car runs great it has 250,000 miles on it but its always been maintained / tuned up.
