I just bought a 2007 Black SI, I have 500 miles on it. I like the car but from day one I have an occasional 1st gear hesitation where you can push the gas pedal an inch or two with no response from the engine until you push the pedal past that point then it's fine, I also have the notorious rev hang although I don't think it's as bad as I've read on this forum. I went back to Honda and they tryed to reflash my ecu and no available updates were available, and my serial number is past the one's that needed the reflash but I thought I'd try anyway. Honda showed me the 2006 service bulletin and I told them I had the exact symptom's and it's still not right on my 2007, but there was nothing they could do.Has anyone else had these problem's with there 2007's ? I guess i'll have to wait until a new service bulletin comes out for 2007's, But it is kinda annoying not knowing if it's going to hesitate or not at a green light. Sorry for the long post, it;s my first post and my first Honda, Great site. Thank's FZ583
