hi all,reading above with interest why not have injectors tested rather than replaced.there is lots of free infomation on the internet and this forum on testing etc .i think i was frank massey who coined the "test and dont guess" phase and this is the way i go .i am mobile and most of the time have customer looking over my shoulder if parts fitting on car dont work he knows about it.i feel people are using forums etc for a quick fix and this is leading to poor standards of diagnostic work.
