Hello All, had a recent issue with my 2013 LR4 (3.0lt SDV6)... After putting my foot down (boy racer style) I got the dreaded limp home mode. When hooking uo to diagnostic got fuel pressure low, a look under the bonnet and I can actually see/hear smoke issuing from the left hand side (so right as looking into engine from front of car) middle injector - injector 5 I believe.
After wrestling this out it was caked in carbon - id re-fitted these in January this year as part of a inlet manifold change so assumed id done something wrong. I've since learned of the importance or re-seating correctly etc. Cleaned up the offending injector (as best I could) and inside the seat, including a re-seat with the correct tool. Re-assembled with new seals and engine started with no fault lights and apparently plenty of power - except... it idles like a pig! And in fact if left idling for some time get limp mode again this time with error code for injector 5 misfire. Weirdly however, occasionally it will idle absolutly fine?! I did notice when refitting that the retaining clip for the electrical connector wasnt present (ie broken previously) - I believe this was missing following my work in January but lots of miles since then without issue.
I do have to admit to dropping the injector before refitting. Not from a great height and not on to anything particularly hard. The good performance when under power suggests its OK?
My question is, could the rough idle, with occasional good idling without intervention, simply be caused by the electrical connector? I'm not sure given it runs under power. Should I have done something in the diagnostic tool when refitting the injector to train it etc?
Any thoughts or advice as always greatly appreciated!
Many thanks
Steve
