Hi All
new here and first post
i just bought me a 206 1.9d LX. We car runs really well and other times it does not.
I could be driving about for 2 or 3 days and not a hiccup, then randomly its runs really really lumpy and the engine will not idle
this could last for couple minutes, and then it goes really well again. It could run lumpy again 5 mins later or 1 day later.
When it runs lumpy, i see a lot of white smoke coming out the back and has a loss of power like it is off an injector and then it just rights its self and away we go.
it is so random. could turn car on and it will idle for 2 hours and not a miss a beat or could turn car on and every couple minutes it cuts out and couple
minutes later again it could idle for 2 hours again and not miss a beat.
Has anyone seen this problem before
Any advice or help be great
Thanks
N

Just an update
I have took the egr value off and cleaned it and made no difference.
Actually 2 days after doing it, the car has got worse.
It is like it is only running on 3 cylinders. it is def off a cylinder
white smoke coming out the back and no power, then all of a sudden is will right itself and go as normal again.
This could last 2 miniutes or two days
it is doing my head in
Do you think it is a faulty injector or is it still the egr value needs replaced
or is it something else
ahhhhhhhhhhhhhhhh!!!!!
Cheers
N

Do a full service including the fuel filter. You may find that the fuel filter is almost full of water or even missing allowing water to get to the injectors.
richpowell91 also has a point; it could be the beginning of a head gasket and coolant could be getting into the cylinders.
EDIT: forgot to say if this is a garage purchase take it back and get it fixed for free.

Take off the flexi pipe between the airfilter box and the plastic inlet manifold and see if the EGR is allowing exhaust gases through when it's idling. I blocked mine off by putting a 10p between the metal pipe and the valve and then putting the clamp back on.

Cheers for the quick replies guys
I changed the fuel and air filter and oil filter already. that was the first thing i did couple weeks ago
I will double check the coolant level. I put a new starter in it 3 weeks ago, so had to remove rad hose and it was getting in my way and i checked it for the next couple days afterwards and it seemed fine.
the we car is great for a we roundabout for me as i got cheap. just wish i could get this problem resolved
will take intake air pipe off (will put pipe back after) and remove the the electrical connector to the egr and then block off the exhaust pipe going into the egr and see what happens
will keep u updated
thanks all

Hi All
Just an update an a question.
Could not get the code reader. Going to take a couple days.
Could not wait, car doing my head in, it has got so bad that it is not drivable, so pulled the injectors out and they are away to be tested.
Car is really really smokey when it runs lumpy, people are staying about 10 metres behind me its embarrassing lol
For a whole day it went like crap, then when i was about to start working on it, boom!! goes like a dream again.
My question is, 3 of the injectors are lucas and the other is dephi.
The dephi one has a wire that goes to a connector, so take it is a sensor of some sort. Why does only one have a sensor and why of a different manufacturer.
just curious
Cheers

Quick question... Is this a DI or IDI engine/pump? Aka... did you use 27mm socket to get the injectors out? Or 13mm socket?
Sounds almost definately like a dirty injector eitherway.

Update
sigh............... 
Got injectors tested and all are fine.
The injector guy, believes it is drawing in air somewhere, either at the filter housing or a lose pipe. Advised me to check all connections etc.
I changed the filter, but problem was happening before i changed the filter.
Over the time period it has been getting worse. Sometimes turning car of and on would resolve issue temporary and sometimes it would not
The injectors came out with a 27mm socket.
What i did notice when i was removing the injectors was that three were pretty tight but one of them was very easy to loosen. Took next to no effort to loosen.
Another, this injector was also very black around the threads but the others were not. possibly could have been to loose and drawing in air there.
its a thought 
any other ideas please
Cheers

Check for leaks as suggested including every air pipe no matter how small that pipe is.
Has removing and refitting the injectors changed anything? You may have disturbed whatever is defective just doing that. It will add to the overall picture.
Are all electrical connections tight including those on all sensors and even connections on any sensors on exhaust?
You may have a loose connection.
Failing MAP, MAF, lambda or bad connection / intermittent connection on one?
Get those fault codes read.
EDIT: How it works(ish)
The issue with most modern cars is that if one cylinder is not running correctly and gives a poor exhaust emmission the car makes adjustments to all cylinders in an attempt to correct it. So an air leak drawing air into the exhast before the lambda sensor the lambda will "see" the car running lean and the ECU will throw more fuel at all cylinders. The lamba can only operate in a very narrow band and the excess fuel can then make it give up trying to cope. There are many other combinations of what will happen with air leaks depending if the leak is in the intake or in the exhaust and what sensors those leaks are before or after. Air leaks make carburretored cars do wierd things but modern engines with their self correcting electronic feed back circuits can be a bugger to diagnose.
Equally one injector failing and leaking fuel and the lambda will see it running rich and lean off all the injectors.
Some of the very latest cars have more sensors, some have a lambda on every cylinder and in that case the fault codes are specific to each cylinder and much easier to find "the" fault.
