Hello I'm Nicolas, I own 2011 Range Rover Supercharged.
Recently it showsme restricted performance and from then on there is no more power engine ( turns square ) 1 cylinder less. After turning off and locking the vehicle with the key 3 or 4 times, Irestart and everything is fin.
Have you ever had this type of problem, please provide ideas for solutions.

Hi there .
Following my question remained unanswered, I seem to have the solution.
Just inspect the throttle body of the accelerator, clean it and check the 2 connectors. In each of the connectors a little WD40 to drive out humidity and oxidation.
