im not that clued up on the 2.8 i must admit,
have you checked the air filter?
could be the thermotime switch playing up,
coolant sensor faulty (it's different to temp gauge sensor)
but someone who is more clued up on the 2.8 layout will hopefully be along to assist shortly

According to Mr Haynes (and asuming its the same engine as early xr4x4's) there are two things that i would look for.
1: Warm up regulator which is a bi metal strip, like a choke on a carb and regulates fuel/air mix as engine warms up. This is located at front of engine next to cooling system outlet elbow.
2: Fuel start valve which sprays extra fuel at startup and is located on right hand side of air chamber.
Removal/Refit of these bits is stright forward...just remeber to dump the pressure in the fuel rail or you'll get soaked in petrol when you take it apart.

ok i replaced evrything on the plenum and the warm up regulator,so i though it could be due to fuel pressure and it getting vapour lock wheni turn the car off when its warm,so i took the metering head off and when i unconected it there was no pressure in the fuel line,i put a different one on and started the car and it started ok and now there is pressure in the fuel lines,
now my problem is with this new metering head when try to rev it it wont rev but if i put my hand in the air flow meter and move it as im reving the throttle it does rev,now before i fitted it the air flow flap moved freely no problem but now its fitted its gone stiffer,
can anyone help me , do i have two broken metering heads maby,

so far with it when i start the car up i can rev it straight away but once the pressure has built up after a few seconds it wont rev,
i tried changing the warm up regulator and that did nothing,
im guessing that for some reason im getting too much pressure and thats why the plunger stiffens up,i think i read somewhere that the fuel pressure does effect how the plunger works

isn't the fuel pressure controlled by the fuel accumulator located on the passengers side at the rear?
