Hi hope some one can help because this problem on my freelander is doing my head in,
Ok, driving the freelander is sometimes ok, then other times when I get to about 1700-2000 revs I get a littler surge of power a rattle from the engine and black smoke as if it was over fueling, over 2000 revs just cruising you get an intermittent tick/rattle and a puff of black smoke if I accelerate hard I get a lot of intermittent rattling and black smoke,
I thought it my have been the Injectors mucking about so took them out had them refurbished and changed the air and breather filters put all back together again every thing was ok for nearly two weeks no problem but now it come back again to haunt me.
Cheers JG

Intercooler hose maybe, when was the EGR or manifold last serviced ?

When you say EGR or manifold last serviced do you mean cleaned? if so yes

It could be the EGR valve sticking open, once it's been activated. If the problem is random, then try unplugging the vacuum pipe and block it, then see if the problem returns .

Cheers Nodge68 I’ll give that a go,
the problems not really random you know it’s going to happen when you take the car out.I can almost stop the problem if I keep the revs very low in each gear while I’m driving like a Sunday afternoon driver but like I said if I want to overtake you wouldn’t want to be behind melol.
I don’t know if it’s my imagination but it seems better when it’s cold.
