I am fed up with the way my blazer is running. I think I have a bad injector cause I've replaced everything but...So would it be possible to just switch over the whole injection sytem from a later model? I can get my hands on the manifold, and the entire injection system from a '98. Will it fit?

 

You would have to do some wireing as well. prolly alot of work. You would be better off just replacing the injectors, since you already replaced everything else.
