Ok so i know somone else has to have this problem, because this is the 2nd 3.0 v6 4runner i have owned that has done the same thing! It will idle fine and rev up when in neutral, but as soon as you put it in gear it just sputters and cuts out and will barely move! does anyone have any ideas or have had this problem? I was kind of thinking maybe it was something electrical, thats why i post it here. thanks!
