she goes a lot better, the 240 that is :)

i checked the little box under the bonnet with the codes in it and reset it
by disconnecting the battery, so i got 1,1,1 . . all ok . . . .

then i went for a good rive and the consumption seems heaps better, but
won't know untill i have use approx 50liters, and see what mileage i did . .
.. .

i did notice that there was a code in the little black box on number 2
terminal after going for a good rive, was . . . 2,3,1 . . . . .
do i have a Bosch LH2.4 or Regina fuel injection, its an 89 240 gl sedan?
and there is only the letter 'A' on the box, which i think means an earlier
model.

if its a Regina, then i think it means:- 2-3-1
Self-adjusting oxygen sensor not operating
Intake air or fuel system



otherwise Bosch LH2.4:- 2-3-1*
Fuel trim (lambda control) too lean or too rich at part load
}If too lean: air leaks, low fuel pressure, bad sensor
}Engine stops when starting from cold; high fuel use or
Fuel trim (lambda control) too rich at part load
Oxygen sensor



i got this info from :-
http://www.brickboard.com/FAQ/700-900/EngineOBDCodes.htm#ReginaFuelInjectionFaultCodes

the 240 had a new lamda sensor and airflow meter put in it the other day.

any ideas what i should do next :)

thanks guys for your input, has been very helpful :)

Unless things are different in AU, you've got Bosch injection. You can tell
easily, the Regina system lacks an air mass meter.
 
GAS as yopu call it petrol as we call it $ 1.23 cents a litre today .Not
only are the arabs intent to kill us infidels they want us broke as well .
 
much better fuel consumption now . . . . 50liters to 500ks, thats better . .
.. . getting the injectors cleaned and main seal in the engine fixed, for an
oil leak.

thanks for all your input guys :)
