hi, could a vacuum leak from loose injector sitting? I guess my real question is:

how tight should a injector be after complete tight the fuel rail bolts. no move at all, or we can still spin the injector around? if we can still spin the injectors around, does it signal a potential vacuum leak?

thanks

 

I don't know the proper spec but I can bearly nudge my injectors from side to side IIRC.

If you have a vacl leak the simple way to tell is to take a can of carb cleaner and using the little tube spray it on the grommet. If the idle changes then you found your leak. If it does nothing chances are your ok.

ahh the good ol injector cleaner, good for so many things, mainly turkey

 

The injectors should be able to be moved a little, however you will need to replace the lower grommit and O-rings every time the injectors are removed after the engine has been run.
