A few months ago I wrote about my 86 Bronco bogging down after warming up to full running temp, and not being able to get the RPMs over 2000 at first then 1500 and so on. It turns out the gas tank had over an inch of rust and other crud in it, and through the course of driving for 15 to 20 minutes all that crud got shankin up and would clog the in tank feul pump. pretty easy fix after, well lets see, new fuel injectors and numbers of sensors. so all's good now.
