Naw, it ain't that bad.

 

Mine sounds just fine .... Its only 50 rpms difference ....

 

Between 900 and under 750?

 

Close enough ..

 

I had my last truck do that to me a couple times in traffic. its the Idle screw, just make sure when you tighten it back down to do it pretty dogon snug. It can and will back out on ya if you dont. Best of Luck!

 

update, i finally got a nice day and tried setting it, "tried" being the key word, i adjusted it 3 times, bringing it up to around 900 on the dash, took it out for a test each time and within a couple blocks it would go back to stalling when i let off the pedal,

 

have make sure the jam nut sis nice and tight ... use some blue loc-tite on it if you need to ... Clean it with some brake cleaner ( non chlorinated so it dries up ) , and then put some blue loc-tite on er and set it and allow it to sit for a bit .. the warmth will cure it ..

 

+1 for the blue locktite

 

ok another update, i tried the blue locktite, no avail the screw isnt backing off, i took it over to stateline diesel in edwardsburg mi to have them check it out, they replaced the overflow valve, sending unit, and reset the timing on the pump, but now when it idles right it now ildes at 1250, but goes up and down, could this be a govenor spring issue below is a video of what it does.


note im not making the truck idle up and down, im only tapping the fuel to show it stalling

 

Woah, I'm out. I would have said OFV. It's almost like your idle is set way high and the fuel shut of solenoid isn't fully engaging, but I've never actually seen that happen so I wouldn't really know. Hm.
