206 1.9 D Running Problems

[genoff2000]

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

Hi All again

So far

I have

1. cleaned egr and problem still exists
2. removed egr and inlet manifold and still no joy
3. Took injectors out and got tested and still does same thing.
4. Left into mechanic and they have had a look and think it is fuel pump
5. Got a new pump, but not fitted yet from breakers today.

I did not realise this, but the immobiliser on my car has been bypassed.

Could this have anything to do with it. The security plate has been removed and a wire is connected directly to the solenoid. Car starts and turns off from the key and no warning lights on dashboard.

Either someone has done this to try and fix the problem and they have replaced the pump, or something else happened to the original immobiliser and someone has just bypassed.

Thoughts please

I take it you are talking pre HDI only you haven't really given us much to go on? Year? Mileage? Turbo non turbo?
White smoke is unburnt fuel. I would compression test it as a low comp will cause this and this in turn could be caused by a tight valve clearance, so you could check them too.

Update......

So yesterday i changed the diesel fuel injector pump and finally the issue is GONE.

The car is evening starting on the first turn of the key. Before i changed the pump i had to turn over a few times to get started.

Cheers guys for all the help and advice.

It was interesting changing the pump, i have never done one before.

Learn something new every day.

Thanks

Glad you got it sorted. You were unlucky with the pump, they usually last a lot longer than that. (The immobiliser bypass is a common dodge)
