hi
i have a 1984 300sd turbo and its giving this loud clatter noise after i have the injectors calibrated. i would like to know the exact pressure bar for these injectors since they a now set at 200 bars, also the transmission shift from 1 to 2 is very jerky and it will only shift from 3 to 4 when you reduce the pressure on the acelerator peddal
thank you

On the blue bar, select search and advanced search and many times these questions will have been answered in depth in the past. In fact, sometimes you will get a better answer to your question.

TWO HUNDRED BAR? Yikes - I'm surprised the engine runs at all. The spec is about 135 bar, usually set to 140-145 during calibration. You need to have them re-calibrated immediately...
