Engine light on again. Injector problem?

[X5smw]

Hi all. 2002 x5 e53 3.0 petrol. 
eml light came on and the wife says the car feels slower. 
when the car is idling, it seems to have a very slight misfire.

i put the small diagnostic reader on it and it came up with lean mix due to low fuel. I’ll rig the car up to the 1.4.0. Would it tell me which injector is playing up or is it best just to replace all 6? 
 

is it a straightforward job or a pain… simply because i have just had my gall bladder out! 
im supposed to rest up, but i have jobs that can be done for the next two weeks! 😂😂😂

Morning Stu  Ouch!!

Fuel pressure check would be my starting place. From memory (old and dodgy) should be around 50psi any thing lower will give the symptoms your getting

If I remember Pelican Parts did some great write ups on Fuel delivery and pressure plus stuff on injector testing worth a look at their site

I have been told it only hurts when you laugh 🤣

Get well soon Matey
