HELP... freelander rough idle

Hey guys, thanks for reading this I appreciate your help,

I have a 2006 freelander td4' it was initially running super rough at idle ans had done for a year or so, it was very lumpy at low revs..
I was advised that this was due to an injector problem, and have now had all 4 injectors replaced...
The car now runs like a dream when cold... Like it was new, but as soon as it gets up to temperature, I take the car for a drive, and at around 2-3000 rpm, it feels like it's running lumpy, and then as it comes back to idle is super lumpy running.... Very quickly it settles down, it's almost as if it's just struggling under load..

My garage seems to be useless and I have lost confidence in them, but as they fitted the injectors I want to be sure that it's still not a faulty injectors before I take it else where..

I would really appreciate some help or guidance in this THANKYOU, I have scoured the other threads on lumpy running but none seem to fit...

THANKYOU,

When was the fuel filter replaced and also the low pressure fuel pump?

Or the fuel harness on top of the engine to the sensor?

I don't have a TD4 but a very high % of posts like this end up being the fuel pump and filter (both under the right hand rear wheel arch if I'm not mistaken). It sounds like the injectors were faulty and needed looking at - but with any problem like this replace the pump and filter in case its masking any other problems - they need replacing reasonably regularly. They also won't cost you as much as the injectors and are quite easy to do yourself.

Do yourself a favour as well and pop into the Introduce Yourself - Land Rover Zone section and put a post up - people will be more likely to give help rather than abuse then. As you've got a 06 car - you may be needing it more regularly going forward - and hopefully can contribute as well

Awesome ,
Thanks guys, the injectors have been replaced, the fuel pump and high pressure fuel pump and filters were all replaced within the last year...

Fingers crossed it's something to do with the fuel rail or pressure sensor...

Thanks for the advice about the introduction bit.. I will do so now.

Cam or crankshaft sensor?

Or am I thinking of the petrol?
