Need your diagnosis please. I'm not sure what this is, but it's the first time i'm hearing this. This is my first supra, and I tried searching if anyone else had posted a video with same kind of problem but couldn't find.. Anyway, I just had a rewiring of the knock sensors, and after the turbo wasn't working and the engine started making this sound when accelerating.
