Does anyone know what the screw on top of the injectors is for I cant find it in my books. Ive pull the injectors and blew them with air and flushed them and blew them again and they look clean but I need to know about the screw, is it like an air /fuel mixture screw and how do I adjust it? When I took the injectors out the screws were about half way in, do I tighten them down and could that be the reason im smoking so bad too much fuel cause they wernt in all the way

Injectors are electric solenoids and not adjustable. I don't know for sure what you are referring to but the only screws involved here are to hold the injector cover on

Each injector has a screw on the top and from what im seeing its a mixture screw, ive been adjusting them and the truck is starting to come around, lot less smoke and starting to get a mid range on rpms, she is idleing rough but shes runnin and seems to be responding to the adjusting screw. Hell I dont know what it is but its working
