Yeah another injector rattle thread 
haha.
I am wondering if there are any external factors that can be causing the rattle rather than just the injectors them selves. For example, too high fuel pressure (Dodgy FPR) unclean fuel (blocked or damaged fuel filter) Etc etc.
I got in my car today and usually I have a fair bit of rattle. Nothing stupidly bad but easily noticeable specially with the windows open. However today it was lovely. No rattle at all, really smooth and quiet. I did nothing different. Its been on the same fuel now for half a tank which is just shell regular diesel. Cant think why it would be so quiet.
It was like this the next 2 times I started the car today and drove it. But then after about the 3rd start and drive it went back to rattling again haha. It is so unpredictable. It's definitly the injectors as it goes when I let off the throttle and I think it goes after 3200rpm as well.
Could there be something really obscure causing it like worn cable sheath or bad connections when damp etc? Which earth point does the injector system use and where does the power supply for them come from?
What do you all think?
