So I've never experienced this on any of my other manuel vehicles... but on my maxima occationally when I am accelerating quickly, my clutch will not come all the way up when i shift. It allows me to shift... and in fact when it doesnt come up all the way it allows me to shift faster which is kinda neat... but I wasnt sure if this was suppose to happen or if there is a spring that is faulty. Has anyone else experienced this issue?
