For a project, I purchased an 89 pioneer with really high mileage with the intention of making it in to a trail rig. Anyway the 300,000+ mile engine was replaced with a rebuilt long block from the local parts store which is working fine but I used the original fuel injection parts from the old motor. The motor has been working great for the last 10k but now I am noticing a hiss coming from the injector closest to the firewall when I start the engine on colder mornings. There are no fluids leaking from the injector and I can wiggle it to make the hiss go away. I know I need to replace them or have them rebuilt because they are pretty old. BUT I recently read a few articles on replacing the old ones with certain year Ford or later year XJ injectors and increasing the mileage a bit over stock. Something about a better spray increasing mileage and what not. Since the injectors are pretty expensive to replace I was wondering if anyone else has used other than stock replacements with any noticed improvement or am I better getting the correct ones for my make/model.
