iam planning to redo the injectors ie. remove myself and have it tested and refurbed.
is there any thing i should look out for not to mess up. my research shows it should be straight forward.
any advice
hogbeast,just make sure to use the nut closest to the head when removing the injectors,a friend tried to loosen it with the smaller nut on top of the injector and it ended up in the buying of new ones. 
i tested the glow plugs, the resistance was about 1ohm according to the spec it must be 0.5ohm. but my car starts fine. any comments.
just a comment about the injectors. i was force to remove the inj by loosing the smaller nut then the bigger nut as i was warned not too. now my question what happened to the inj that you advised not removing it by the smaller nut?
