ok, shawn or rev can probably answer this the best but someone else may know as well. what do the injector plug colors(injector end) mean? the 2000 injectors i have in my storage have only 2 holes at the tip and the connector is green. the ones from my 94, i used them on my 2000 engine swap btw, are red with 4 holes... im thinking that the 4 holed ones will be more reliable in that they have more holes to get plugged before i notice a problem. but is there a difference in fuel flow or what?
