Hi There,
When I start my Freelander td4, the engine reves are erratic (revs up/Down) after a few revs of the engine it settles down quite a bit. This will also happen when the engine is warm and restarted
Many Thanks

This sound like an air-flow or pressure problem.

air filter?
pcv valve? - dipstick test for pressure?
turbo boost control solenoid vent / filter?

If not these when was the fuel filter last changed?

HI,
Replaced all filters about 10 months ago.
I HAVE DONE ABOUT 10,000 MILES SINCE THEY WERE CHANGED

Oh dear - that means that I'm stumped then - for the moment.

Much head scratching called for here.

Lumpy idle could be LTB00052 related.

Possibly sticky injector - could leakback test it.

I change mine every 5k.8k at most.
I had rev counter problems ,which turned out to be a CPS (crank position sensor).

I Decided to replace both fuel and breather filter for the off chance they might be clogged,
Thanks for your help, will let you know how I get on.

Could also be the fuel pressure sensor. The one on mine had different nominal and real values and the ECU kept trying to compensate, hence the erratic idle and eventual stalling.

It was just a matter of cleaning it and adjusting the contacts. So far, so good
