    The section you want is towards the back, ie the 14CUX 90 or so on.
    This refers to the 3.9 US version , so disregard the bit about 02 sensors if you do not have them.
    Happy hunting.
    Bythe way , the coolant temp sensor is the sensor with an injector plug on it, on top of the front RH side of the manifold, to the rh of the thermostat housing, (RH looking forward from the inside of the car.)

    Exclamation Fuel Injection System

    Thanks for the file I read through it and have some work to do! I looked for the ECU under the seat but it's under the glove box? least I think that's it with the multi plug. I'll check out the Coolant temp sensor and fuel temp sensor ohm readings once I find a decent meter.

    Thanks guys

    Wow! Thanks guys... I have read through this thread and the british.org website post and have fixed my idle problem.

    I am new to rovers (rebuilding a landcruiser - cannot wait to get back into it!!!!) but after replacing leads, plugs, cap and rotor for better feul economy I have learnt alot. Vacuum advance unit has just been replaced through advance diaphragm options, caboutlure, and have cleaned up the stepper motor and MAF connector... my stepper motor plunger had some corrosion on the tip - the opposite to getting gummed up and oily... some fine emery paper and carby cleaner and I now have a rock solid idle and much better throttle response/power.

    Will check the fuel economy next tank...

    Thanks again
