Alright guys ,I have looked til my head hurts !!! I don't want to seem too dumb here, but I need to know how to bump up my idle to eliminate cold start lug . My truck idles about 500 cold and 750 warm . Seems way low to me cause it causes extra spool lag at take off ! Also would like a little more fuel - not much just a little to help with pulling my camper ! Thanks for some extra help cuz I know nothing about a cummins-my first one !

 

here is a really good write up for fuel mods. most of it can be done for free, however i recomend gauges before adding fuel.

Thanks for the information cmac ! I'm gonna get on this today and hopefully getr runnin a lil better . Cause the cld starts are drivin me crazy ! I have two solenoid switches on the frame next to the in-fender on the drivers side . I have no idea what they are for , but one has some broke switch wires , so i think theyare for the intake and fuel heaters , but i dunno ! Any ideas ?

 

might be for the grid heaters but i'm not sure

 

Correction on that idle speed, it's about 350 cold and 600 warm . A little too low !

 

I got some pics of em . Try to get these up soon , so ppl know what i'm talkin about !

 

heres the pics of the mystery solenoids !!!

 

The Idle Should Be Around 750 To 800 If I Remember Right. I Turned The Idle Up On My Buddys Truck And It Fixed His Hard Start Issue

 

hopefully it will fix mine ! This thing is driving me nuts !!!!
