hiya all, Just had my injectors cleaned and flowed after some running problems they are flapper type and rated 185cc/min @ 43.5psi.... Bosch items 280 150 105. The best they can do is 173cc/min lowest reading 202cc/min highest reading. Works out at 14.3% difference between them. Are these still ok t...

hello again, Well removed the injectors today and set the fuel pressure at 36PSI. Using a very crude method i ran the injectors for 1 minute and measured the results in a container. hhhmmm and i found the following cylinder 1 - 140ml cylinder 2 - 145ml cylinder 3 - 122ml cylinder 4 - 155ml cylinder ...
