I have taken the fuel injectors out of my mustang and was wondering if anyone knew how to tell if they were bad, I tried to spray cleaner through them but can only get two of them to go through starting at the spray end spraying backwards with the red hose spray nosile on the can. The other two I can get to spray through. I know the injectors have a plunger in them, but does anyone know which two are bad; the ones that I can't spray through or the ones I can?

The only way to know for sure if they are bad is to either test them on a flowbench or while on the vehicle with a set of noid lights.
