Hi everybody another problem my Lenny has started kicking out some black smoke under exceleration ,I dont think its a turbo pipe as there nearly new silicon and there is no whistle. so what else can cause this can it be the MAF, injectors were changed from tropical to standard when i came back and were fully tested by Bosch.

So any Ideas greatfuly excepted Sorea
Ps managed the drivers door lock harder than the passenger side my hands and nails need some intensive care.
Still need to do the handbrake
 
I have unplugged the MAF and it makes no difference I have a chance to use a lift on wednesday so can get it up in the air , the overfueling only happens on full throttle when joining motorways or overtaking and stops the minute you ease of the pedal, what else should I check,
 
Ok so any suggestions Lads I really dont want to go into a Land rover garage I think I might be able to borrow a diagnostic laptop so will try pluging that in and see what happens

Have you checked the air filter?
 
Even though you have new hoses on, it doesn't mean that one isn't leaking air under hard acceleration. Check all the jubilee clips are nice and tight, and that the hoses are about 1 inch over the lip.
When you have it up in the air, check the hoses that join the turbo itself.
If you still have the EGR valve on, make sure one of the 4 bolts holding it on haven't worked loose.

I guess I'm a bit fick about these things. What is the MAF for?

It has been explained many times to the point of nauseam. On a petrol engine it tells the ECU how much air is being ingested and the ECU then fuels accordingly. On a diesel engine it tells the ECU how much exhaust gas is being ingested so the ECU can control EGR operation.

Oh, I see.
So does that mean on a car with the EGR bypassed it is irrelevant then?
 
Yup, definitely a parallel universe.
Exhaust gasses my arse.

Please yourself but your arse is wrong. Perhaps you could give us the pleasure of your knowledge by explaining how the MAF does this on an engine throttled by fuel. Which for any given engine speed, throttle position, manifold pressure ALWAYS has the same amount of charge in the cylinders.
