morning all , just thought i would give you all sothing to think about while at work today to keep you from getting bored!!!!!now i have recently bought a 96 n plate v8 disco and im well pleased even though it has a few probs, small ones but all the same a little annoying!!!right this is the worst one im getting my ear bent about.when starting she starts real quick and the revs rise to around 2k then drop to feck all and she stalls,when restarting it again it starts spot on but the revs rise to 2k and then drop to about 250. it will then rise and fall between 1k and 250 until you rev it and the thing that worries me is that it does it when its hot or cold. now i have changed the leads the coil the air filter the plugs dizzy cap and rotor arm and its still the same?any ideas lads (and before you say maf plug i have checked that)cheers paul

shaun and co:
had a similar problem once- there was a tiny hole in the fuel pipe so fuel was draining back into the tank when the truck stopped and air was replacing it. the whole was so small though that air could get in but fuel couldn't get out so there was no tell tale leak.

greasemonkey:
Hi being an N reg it will be fuel injected
therefore will have a temp sensor
this will set the fuel amount depending on temp of engine
if knackered will cause this fault by either over fueling (revving)
then the lambda says too much fuel and cuts it out (dying)
replace sensor all will be well
cheers

peasey:
ah mate that sounds spot on and to be honest i have checked every thing i can think of except that!! i dont suppose you know where abouts it is do you mate cause i cant find it in the haynes manual.is it the thing that bolts to the side of the aluminum 3.9 inlet manifold?

greasemonkey:
HI mate
sorry a vx persom i am just going for the engineering answer
but it will be on the water temp side
so look by the thermostat etc
cheers
steve
