V8 trouble!
Skibum346:
Whilst an efi engine will generally sort itself out, the ECU is only as good as the readings it's getting from the sensors... see if you can "borrow" a known working air flow meter and change it, see what happens.
The other place you could look is at the Lambda sensors on the exhaust. If they give false readings then the ECU will try to make the mixture leaner or richer affecting performance.
There will be loads of other sensors but these are starting points.
Good luck

I'd be measuring the TPS output, it sounds like you've got a dead spot.

TPS Output....? :(scared):
skip:
Throttle position sensor :D
both your suggestions make sense, there is a landy specialist near me with a rovacom, I think an hour of his time doing some realtime diagnostics could be money well spent.
I'll get the multimeter on the TPS first as it's free. unfortunatley I don't know anyone with another V8 I can swap stuff from. :(

Hey skip!
My bro's got a P38 4.6 LPG but his wont run on petrol because the engine has been tunned to suit LPG. this maybe the same for urs if it wont run on petrol but will on LPG, but if its the other way round then it may need re-tunning to suit.
