Freelander 2 (LR2) Help

Hi all I have a freelander 2td4 and have trouble around 2 thousand to 3 thousand revs it seems to hesitate and jib and spulter then clears I have changed the fuel filter air filter mass airflow sensor crankshaft sensor and no different it seems worse when it is wet I have a load of codes but just don't know where to start

Misfiring at speed can often be tracked down to a faulty crank sensor. It's cheap and easy to change.

Done the crankshaft sensor

What codes are showing?

Loads .po103,po100,po183, po380,p2297,po299,po2e0,po2e1

Hello! Many failures are due to a dead battery. Have you checked it has the correct charge? how many?
I'd do a 100% load first, then erase codes and see if they reproduce.
Part of the failures may are produced for the mass air flow or the variable geometry of the turbo. Air filter is clean?
First try to disconnect the mass air flow and if the car improves you already know that you have to change or clean it. Luck.

I have put a new one on it

What code reader did you use? All LR codes have a 2 character suffix after the 5 or 6 character prefix.
The 5 or 6 character prefix gives the location of the issue. The 2 character suffix gives the actual issue.

For example the PO103 is a code pointing to the MAF sensor.
However there should be a suffix which points to the issue, 11 would be short to ground, 12 would be short to battery, 13 would be open circuit and so on.
There are a couple of hundred suffix codes, covering all manor of potential issue, so they're very important in identifying the issues.
