theakerstwo Posted November 30, 2012 Share Posted November 30, 2012 Pull fuel pump and send to fuel shop. Its the governor worn out or a sticking rack.

skip Posted December 1, 2012 Share Posted December 1, 2012 Does it make any difference if you bump the idle up? Like theakerstwo said above, sounds like governor is worn. Has the pump got the rectangular plate bolted on the top behind the Vee section? If it does you can take it off and check both racks to see if they are free Quote Link to comment https://www.bigmacktrucks.com/topic/28598-endt866b-hunting/#findComment-148811 Share on other sites More sharing options...
RAYCO Posted December 1, 2012 Author Share Posted December 1, 2012 Thanks will check. as far as worn, it has 138,990 original miles, I know hard to believe but a fact, so it has been sitting around a long time(bad deal for a truck).
