My throttle body doesn't have an idle adjustment screw
this does not have one. it should be on throttle body and adjust the linkage. on right side og picture.
It's the little screw on the left side in this image.

Sorry guys I overlooked it. It's definitely there. I'll adjust and install tune. Again sorry. I felt for it a few times
No hijack intended here, but my issue may be related? Do I need to adjust the same screw or the tune? Any help is greatly appreciated.
I have a junkyard 6.0L with 317 heads, stock cam, stock injectors, stock everything as far as I know but it will not idle once it is up to operating temperature.
It is fine cold and drives ok, but as soon as I come to a stop it will sputter and die ( have to hold part throttle while cranking to get it to restart )?
It is drive by cable with a 4L80e transmission and I am running a return style fuel system with a stock pump in the tank.
I will try to upload the bin, but new to all of this. Under hood_IMG_3604.jpgInjector_IMG_3605.jpg
Some Fool: First you need to make sure your engine is mechanically sound and all wiring is correct. Have you tried all the previous suggestions? FPR leak, vacuum leak, etc? Probably not the throttle stop as it runs correctly cold. Has it ever idled correctly when warm? When warm and you hold the throttle open does it idle smooth, or like it is choking out, running rich? Does adding a bit of propane (add fuel) help? What operating system are you running?
If you are sure all the above is correct you can start over with a fresh .bin. http://www.gearhead-efi.com/Fuel-Inj...light=12212156

MO LS Noobie. Excellent advice. In looking at the FPR there was a crack in the boot on the vacuum line. I will replace it an try again.
