Ok little story. I was cruising through my town this afternoon and out of nowhere there's a sentra with that "type R" badge on it with a fart can right on my tail. I change lanes and he flys by. I end up pulling up to him at the light. The guy begins feathering the gas with his fart can "purring" at me. I ignore it but he starts revving it and inching forward. I can't take it any longer and rev the shit out of my car and he does the same. No race ensues as I was going a different direction sorry to lead you on. The point of this post... When I was revving it up(close to redline) I had it in first with the clutch in. When I got the revs way up the car inches forward slightly. I'm sure it's not a great idea to rev it way up with the clutch in. I'm not mechanically savvy AT ALL! So I'm Asking if its bad that the car moved or if that's normall or what. Thanks for any help
