I recently acquired an m1031. Unfortunately I inherited the truck from my father, and it had sat unstarted for several years. It started right up with two fresh batteries.I noticed right away that when letting off the throttle that the truck felt as if it was going to stall. It also felt like it was catching up so to speak when letting off and reapplying the fuel. I scoured the forums and checked fuel delivery, air intrusion and adjusted the idle a bit higher. After approximately 500 miles,I noticed that the motor was slightly louder than normal, and down slightly on power. The idle seemed as if it was lower again. No signs of black flecks anywhere internally in the injection pump. Time for an injection pump? I have a reman HD civilian pump, but really didn't want to change it if not necessary. Thanks for any input.
