The other day i was driving my genesis and it started started making some not so pleasant noises. It typically happens when coasting in gear after downshifting. It does not make this noise when the engine is under load but as soon as i let off the throttle it comes back. Sounds like metal on metal contact and as the video shows it goes away when i pull on the intercooler piping, probably because its moving the turbo.. If you have any ideas what might be causing this please leave a comment. Also i forgot to mention, there is a CEL (P2187) 'System too lean at idle Bank 1'.... I don't have much knowledge when it comes to diagnosing automotive problems as I'm just learning things as I approach them and I haven't run into something like this before. Any help is much appreciated.
