Ohh thanks mate big help, yeah I just wanted to know, cause it flutters. Sounds neat, but I heard blocking them isn't good for the engine and car, it can cause backfire which reforces the air back into the engine. But because it's my daily, I noticed she's a lot heavy on fuel. I know as much as these cars are nice machines, I'm also aware that there not your average fuel bargins. But in saying that, mine uses a lot more then average, and I don't even drive in sports shift much little loan put my foot down as I'm only on my p-plates, so I might need some help there. I admit, I respect my car, and because I paid for it with my own money no loan, no finance, no "daddy's" money, you could say I'm fussy and am very proud to be able to own one of these espeacially it being my first car.
