Freelander 1 Overfueling

I'm sure you basically know what you're talking about Wammers.

I'm also sure I know enough to know the difference between MAF sensor, MAP sensor and Fuel Maps.

I'm also sure that others are not as thick as you make them out to be.

One last thing I'm sure on.... is that you are wrong and that you know it - sorry that's 2 things.

Well the Fact that you did mistake Map sensor for Fuel Map. Says a lot of things. The engine accelerates by injecting fuel subject to throttle demand. The driver pushes the throttle pedal down to a certain point and the ECU injects fuel to attain that throttle setting. The engine reaches the requested speed as indicated by the speed sensor and the ECU adjusts fuel to maintain that speed subject to varying load conditions. If the load conditions change beyond that which the fuel Map is capable of delivering without causing smoke the engine will slow down, continuing load will cause the engine to stall unless an higher throttle setting is requested to overcome the load being applied. There are other things to take into consideration on this type of engine but pretty simple really. Basically you suffer from the same thing as most others, you read technical descriptions and do not have the knowledge to interpret them. If there was no emission control system with feedback fitted to the engine a MAF sensor would not be required. The engine would run quite happily without one.

I'm saying you clearly aren't interested in anything other than your opinion. You won't listen. You won't take on board any evidence presented to you. So based on that its pointless arguing with you. Land Rover themselves can tell you you're wrong and you wouldn't accept it. We've both been here before as have many others. It's pointless. You're happy in your world with your old fashioned diesels where you're quite right. But whether you like it or not things have moved on. I'm not going to explain it again as you really aren't interested. Go back and read the posts and links. They aren't fabricated to wind you up. It's documented fact.

He isn't interested DD and does not understand at all- - many many '#old# diesels - when he was in nappies- smaller ones than now I must admit - the nappies - not the butterflies)) were intake butterfly controlled AIR FLOW CONTROLLED)(which he 'forgets' or does not know- probably the latter...)
The vacuum controlled pump units RELY on a partial intake vacuum from the depression in the intake due to the butterfly actuating the fuel pump/ Hence - air flow controlled.... LONG before this fitter was changing exhausts.
The simple fact that modern units use sophisticated air monitoring to adjust fuelling is only a refinement on things that have been around for 60 years or more. I am amazed that someone with the claimed 'experience could not be aware of such a standard system. or have the slightest clue as to how it works.
The only real answer is a couple of months experience repeated many many times - as per a kwik fit fitter.

You are good at reading technical stuff but are not good at understanding it. That is the problem. Happy amateur with big ideas.

Well chaps I have replaced all the turbo hose clips with clamps the manifold has been of and cleaned (not that it needed it ) the Maf sensor tested by bosch is fine turbo vac filter replaced Air filter back to standard fitting.toilet roll removed and cyclone unit fitted Looks to be A OK.

Thank you all so much for your Ideas one of them cured it.

Also its been really interesting following the conversations of the reasoned against some of the very hidebound

Thanks again still have to do the Handbrake cable and think I might change the rear drums so I will probably asking for advice soon.

Sorry your perfectly reasonable question got hijacked by a bunch of eejits but glad you enjoyed the nonsense anyway.
Glad to hear the problem is now sorted but how'd you get the MAF tested by Bosch?

How old and how many miles on the car, My O2 has had new brake shoes recently but the drums are fine.

Its an 02 two door 189000 69000 of that on African roads and tracks, the kind gent who lent me his garage and lift works for Bosch Automotive training and took it in.

I take it your talking about Km and not miles. I'd be surprised if the drums are shot, especially in a warm dry country but unless already replaced the shoes probably will be.

Out of all of them I'd say air filter, sounds like you had an aftermarket type?

Tropicalised filter kit with a mesh pre filter would have taken a photo if I had thought of it before I threw it away.

No miles. My dad bought it for me in 2008, the VCU was not reconditioned untill 110000 clutch at122000 has gone through about 4 sets of disks and 1 of side drive shaft other than that tyres and servicing oils and filter every 4 to 6 months depending on where I was.

Black smoke is either to much fuel or lack of air. In your case it would appear lack of air. Well done on sorting it.

Drove up to London today with a run round the M25 no black smoke at all plus is much quicker of the mark and looks to be returning better consumption.
