engine rpm drop at idle?
While sitting in neutral and when I rev the engine, as the rpm drops it drops below idle and goes back up to normal idle rpm. When it hits it lowest rpm it sounds like the valves are banging on the cylinders. I know others had this problem before but what can I do to fix this? It doesn't happen all the time. I also made a video that I will upload when I get home.

I hope it is a simple thing like a dirty throttle body or just a bad stock tune.
I would assume either one of those would fix it. The thing is, I only have 24XX miles on my car. I doubt the throttle body is dirty. |

I've got the UpRev tune, but I don't remember revving it seeing it drop like that since it's something I hardly do. However, if I let my car idle for several minutes or warm up there are times idle drops momentarily.
