I have an '88 Pathfinder 3.0 v6 that has been giving me trouble for the past 5 months. I just replaced the throttle body (entire unit, sensors too) and now I have a whole new problem. It used to surge up and down erratically, but now it wont even stay running. I think its flooding itself out. It also has a high pitched whistle (no, I dont have a vacuum leak. Ive checked) and will run fine for a few seconds then stumble and die. Ive been struggling for months with this problem, can someone please help me?
