Changed fuel filter-no noticeable difference,Removed aircleaner,turned off aircon(alittle better as expected) Is slightly better in neutrel than with the cluch in whilst in gear but still idles rough.
I had the problem before I got it chipped thinging the reset chip may improve it but still seems rough.
The spotties and antenna base viabrate so that i how bad it is.The car has done 200k no work has been done on the fuel system bar the injector harness.Any thoughts?
Cheers Ean

Start with basic troubleshooting:

1. Have you ruled out the engine mounts are not collapsed - causing vibration to the chassis? This can be confirmed by carefully supporting the engine with a trolley jack - taking the weight off the mounts whilst idling. If vibration goes away - there's your main problem.

Similar to MarknDeb above, replacing my mounts stopped all engine vibration in the vehicle.

Just to let you know,pulled the red plug on the ECU and was amased by the amount of oil present.I thought it may have be cleaned when the stealership fitted the new ECU,(at $120 p/h you would think so,but didnt see no charge for any contact cleaner so can only guess) if they did then I will be cleaning it weekly.Will check it again in a couple of days just to see..Car seems back to normal so another lesson learnt. Thanks to all who offered thier time and advice.

Ean,
In their defence, I have fitted heaps of the upgraded looms etc and always advise customers that there is a high probability of having to clean the plugs again, due to oil remaining in the engine harness. Usually 1 or 2 cleans over 6 months and the oil is all gone. LR actually replaced the whole engine harness in the past during warranty claims for this problem:o
Glad it's fixed though!:)

Thanks for your help and advice JC,im sure in anyother place where there is more than 1 option to have L/rover software available I would agree, but this is Darwin and until you see/hear the attitude of the service section you would proberly understand my reasons for the comment.
Thanks again,just going to check the engine mounts after reading the last thread,

Hmmm, disappointing when that happens. Time to check out a Nanocom or Rovacom Faultmate or similar. VERY useful for late LR owners.

Core Problem Now Fixed

For those interested in the end result of this thread, Ean's vibration issue was fixed by simply replacing the engine mounts.
