Well,
as I was getting some P1179 codes, and I had fixed all the vacuum lines, it was time to attempt a clean up of the MAF.
The Mass Air Flow sensor was dirty as it was the whole intake system.
Got it apart did the clean up using the proper cleaning tools (Used CRC for MAF and some carb cleaner for the rest).
And now the Disco purrs like a cat, it seems to be smoother at no gas or little gas and gutsier when asking for power.
Of course, this all could be an illusion, but time will tell, maybe I won't see the damn code again, for a while anyway...
Also, just before the desert trip I changed oil and filter (Castrol/K&N3001) at +/-107K
