DoubleTop:
try unplugging the thermostat, my v8 was extrememely picky on getting the right amount of air intake and that was massively affected by a stuck thermostat.  What was the temperature (ambient) when problems started?

DT.

mark-d:
i would look at the coolant temp sensor

Range Rover Blues:
The engine ECU can also turn the air conn fans on, when it sees fuel temp get excessive for example (even with the engine off, if fuel temp exceeds 60 degrees) plus there is a thormo switch on the thermostat elbow that turns the fans on if the engine gets too hot (there are 2 switches in fact).  Then the ECU has a differnet sensor to the temp guage, though they both sit just inboard of the thermostat on the front of the plenum.

Check the coil, it shouldn't be running hot.  I swapped mine 2 or 3 years ago, guess what? it's gone again.  It would start, idle etc but wouldn't run on LPG as the tank got less than half full and would start to missfire if I had been in traffic, very odd but it's fine now.

If it's a single point without lambdas is it a draw through (fully mechanical) or does it have an electronic control?  I'd guess at the former because most single point ECUs connect to he throttle posistion sensor and one lambda, often this has to be added so check to see.  If it's a non-genuine lambda it might be a cheap one, however this wouldn't then effect the EFi.

If you don't have lambdas then your engine shouldn't run without an AFM, mine doesn't.

It could be any of the sensors or the ECU itself, whay surprises me is that the car had all those bits swapped once already, so what's happened :-k

Range Rover Blues:
Here's a tbought, can you start up on LPG and if so what happens? have you tried it on LPG with the petrol pump disconnected to check you don't have an injector stuck open for example.

one advantage of older single point systems is that they are independant of the factory ECU.

As for the breakdown, join the caravan club and take out their mayday breakdown.  Not just because it's far cheaper for the same cover, nor because the cover extends to breakdowns on your trailer, or even the fact that they will cover you for a trailer up to 23 feet (as opposed to the 14 feet covered by the RAC) but mostly because they cover you for a return trip if you can't get fixed.

The last time we called them out, they turned up first time with the right recovery truck, took us home then offered to come back in the morning and take it to a garage ;)

gnasha:
have you cheaked the air flow pipe our old one did same ended up being a hole in pipe wrapped it up with gaffer tape lasted months till we got a new pipe
