Just an update on todays work. . . thanks to all those who offered advice.
Everything went pretty well, I used vice grips to loosen the injector cap screws. Then with the help of a mate, we inserted a screwdriver into the hole in each side of the injectors and levered them out over the shaft of another screwdriver, across the screw tabs. (four screwdivers) if that make sense.
we re-used the o-rings, there's two on each injector, one top and bottom.
once it was all back together i punched in some correction and fired it up. . .
my concern is the idle is very rough. like its on 5 cylinders. it definately goes ok on boost and driving around. just idles like poo
any suggestions?
cheers
