it was very wierd. I didn't do it again in any other gears or later from first to second. There was a very faint smell of burnt clutch(!) only very faint though, but it worried me senseless. The fact I floored it rather abruptly made me feel like I had abused the car, which makes me feel sad

I have checked the net today and this points to the master cyclinder, apparently. Although a lot of peole saying that this happened to them once opr twice but without long term problems.
Should I get it checked?
