governor problem???
 

i think my governor is bad but im not sure. my truck wont idle in gear or when it is cold. if i keep my foot on the trottle it will keep idleing fine. it runs perfect other than that. no grey smoke or any signs of lack of fuel

May have to turn up the idle screw.

it already idles a little high

It should idle at about 750 rpms in gear with the A/C on - if its an auto. Mine with the NV4500HD idles at 850 but with a manual that is not really a problem.

i dont have a tach but i know it atleast idles around 850-900 in neutral. it wont idle in gear

Maybe someone else will chime in and answer this, but could it be the KSB?

The KSB advances timing until the engine temp reaches about 100 degrees. I wouldn't think that would cause the problem. Cumminskid92 what mods have you done to your pump?

Bob

AFC spring out, fuel pin ground, max fuel about 3-4 turns

My first thought is that you might have to re-index the the throttle shaft but that is only a guess. Does your idle screw touch the throttle linkage? If not and you see 800+ RPMs then you will need to re-index the pump to get the idle into the safe range. Also did your problems start right after the pump mods or later?

This is probably the problem
