Today I have done a leak off test on my injectors, I have already used a bosch ESI[tronic] diagnostic from work which told my injector 1 was out of spec all the rest were showing a green result. Injector 1 leak off was over 130 ml injector 2 60 ml injector 3 95 ml injector 4 60 ml i used the Delphi recommended way of doing the leak off test below.

2 minutes running at idle followed by
30 seconds with the accelerator held at 3800 rpm followed by
30 seconds at idle followed by
30 seconds with the accelerator held at 3800 rpm followed by
30 seconds at idle followed by
30 seconds with the accelerator held at 3800 rpm followed by
30 seconds at idle.

do you think I will get away with changing injector 1 & 3, or should I do them all, the car has done 130000 miles. A link with pictures of the bottles showing the leaked off diesel is below.
