hi i have a problem with my idle, i tried searching but couldnt find someone with this exact problem. When i am driving and let off the gas the idle will drop really low, sound like its about to die, then rev back up and back down again and so on. Finally after fluctuating for a little bit it returns to normal. It is really bad when i let off the gas and make a sharp turn, it drops really low and sometimes even dies. Has anyone had this problem? thanks for any help
