On a nissan or infiniti that throtle actuator system is SOOOOOOO sensitive. its an understatement. If the throttle door has been touched sprayed cleaned or even looked at hard. it need replaced. I cant belive how sensitive they made this thing. it Might not be showing incorect readings at closed and wide open but its got ish! try the relearn.
