200 Tdi Idle Problem


Recommended Posts

I've recently had a problem with my 90 due to corrosion of the fuel filler pipe.

After a trip to Belgium for some off roading and the drive back along extremely wet roads my normally very well behaved 200tdi began to die at tick over.

Having sorted out the corroded filler pipe, cleaned out the fuel tank of mud and contaminated diesel, replaced the lift pump and filter the engine does run better but it won't run at "normal" tick over. I'm also loosing top end speed which I guess equates to reduction in power. On start up the engine is more smokey than usual - the smoke is white not blue.

Before I book it into my local LandRover experts I'd like some advise as to what to look at next?

If the fuel filter was doing its job then that should have stopped the crud coming through anyway. what the milieage it may need new injectors or worse the pump. Before you you anything though check the pump timing is correct.

what about carp in the stop solinoid....

or poss rubbish still in the injector pipes... undo them and crank the engine over to clear them.. whilst there you might as well remove the injectors and clean them up, and if they are out you could do a compression test to see if your head is still sound.

white smoke -- is that water or unburn fuel? can not remember.

the other option - - you could always tweak the go pedal cable... just twist it a little to see if that makes any difference. (it will give you a higher tick over rev)

just a few ideas...

White smoke on start up that disappears once the ngine is warm is unburned diesel (smell it) Was your timing belt replaced recently? A slack or stretched timing belt can cause these syptoms, as can incorrect pump timing. You can get your injectors tested at a diesel specialist and it's a lot cheaper if you remove the injectors yourself and take them in.

Thanks for the helpful suggestions - I've already tweaked the go cable just to avoid the engine cutting out as soon as the revs drop but as soon as I try to reduce the revs to a normal tickover she dies.

I'm pretty sure it must be a fuel delivery issue so I'll have a go at some of the suggested solutions around the injectors, then work my way up to the more serious bits of work!

Thanks again
