Had a truck do that a few years back. Customer had tried washers instead of a gsk kit and in the process bent the studs for the governor spring retainers. Acted identically.

Have to agree with manonbroke, lefty loose will screw out bolt and increase idle. A touch of loc tite BLUE will keep it there with the lock nut snug!

a touch of loc tite blue & jamnut will hold it till you adjust it the next time!
sorry bout the repeat, did'nt scrol down far enough

 

would it be worthwhile to change out the gov springs? they want upwards of 2000 to rebuild the pump.

 

I think they just want to rebuild a pump and get paid.

 

ill agree on that i just spent 1200, getting the other work done there

 

I can't believe they did $1200 worth of work and gave it back to you running that way.
Sounds like the kind of bullshit I expect from a stealership.

 

I wouldn't have the pump rebuilt. I'd do some exploratory surgery and check the governor assembly. It may require pump work (the issue your experiencing is definitely an internal pump issue). But don't think I'd let a shop that charged you that much without providing results do the work. A couple hours or so wouldn't surprise me but 1200 and worse than it came in...no thanks.

Diesel Injection Service, the 2000 was going to be put on top of the 1200, i told them exactly what was happening when i took it in. kinda irked me to get it back this way considering that they said it would be fixed for 1300, but what kinda bugs me is dont you have to take the pump off the truck to set the timing? shouldn't they have checked everything out then?

it is running better than when it went in, but still stalling, i will say going down the road at any speed feels better than before, it would just be nice if i didnt have to double pedal the damn thing

 

I can't say if they charged fairly because I don't know what they actually did. I know if I'm talking to a customer that I'll indicate "this is part of your problem? It may not be all of it". I actually loose some customers doing so but we can't know it all and get it right every time!
The pump is timed on the truck. To know what's really going on it would need to go on the bench. By checking the governor and idle springs you can gain direction but it still may require a bench run. has anyone messed with the governors?

no the only part of the pump that has been touched is the afc and fuel plate
