I am having a problem with the rpm erratically fluctuating as the outside temp has decreased. It fluctuates at idle and while driving at a constant speed. Also causes throttle resistance and int engage of od and slight jerk when shifting gears. There is a technical bulletin referencing this kind of problem NTB01011
which points a problem with the idle speed control unit. Once vehicle is totally warmed up it seems to go away( after 30 min ).
I am not sure at this point what they mean by the idle speed control unit. Since there is a TSB issued this problem has occured
and will occur on these vehicles and probably other nissans as well.
Any help would be appreciated.
