P38's do not like water. Diagnostics would be my suggestion.

You might have got number 4 injector wet. That can cause issues, especially if you blast it with a burning stream of red-hot steam from a jet-wash that can cut through bricks. Just ask @tomcat59alan ...

Thank you for your reply, I washed it with normal water nothing else and it was cold. If the problem with number 4 injector, should I replace it or is there any suggestion?
My regards
 
Thank you for reply, the only msg I got is Temperature air sensor -35. When I diagnose.
That is for the IAT which is not fitted to your car so the default -35 is shown.
If you have diagnostics, look at EDC temperature sensor, crank sensor, needle lift sensor and MAP sensor with the engine running. Try unplugging the MAF sensor. While you are at it you could check the modulation.
 
Hi guys again
Thank you for your replays, I am still suffering from this problem and other, I change the injector no4 I bought a used one and the problem still, I bought also from eBay (hot start kit) and the manual say , it has for wires 2 blue they should connect one to the signal wire number 1 in the coolant temperature sensor which I don't know where it's located and the other one the ECU, and the 3rd cable is red which it should connect to the 12v ignition and the black one to the ground, all of this I don't know where they located, and the coolant temperature sensor as well.
Also when I start driving the car there is no power and it's so slow even if I press the pedal to the end, but after 4 -5 sec it's drive faster.
When I drive on the way the center lock start locking and unlocking sometimes.
Please help me with some pictures or video if there is a solution with more explanation, I love Range Rover but I don't have any experience in the mechanic.
Many thank in advance.

Have you downloaded RAVE yet? At the end is an electrical section showing all wiring with pictures of the location. RAVE is linked in the Technical Section.

@martyuk on here refurbs the locks with uprated microswitches but people keep failing to return their old units so he might be short.

Also, the boot switch degrades over time and can start leaking water. It earths through the driver's centre microswitch but if water is present in the switch it can cause odd behaviour.

@wammers is the diesel God. For slow pickup I just don't know. It has a throttle pot. Maybe the first part is worn? Or maybe the fuel injection isn't being advanced enough on acceleration? Pump timing too far retarded? I don't know and am just guessing but Wammers will know. @Datatek or @kds might know as well.

Needs to go on diagnostics for the engine problem.
Sort the power problem BEFORE fitting the Hot Start mod or you will just be adding to the potential problems.

Does it do the 4-5 sec thing when cold?? Could be a hotstart issue effect.

Look up ‘ghost locking’ in search bar. @DanClarke is good with this there is also a test sheet on here somewhere by MartyUK
