As Above, It's a TB42E. It's fine on Gas with no probs there.
Things i'v replaced or changed or Checked.
Brand New Plugs,
Brand New Leads,
Brand New Dizzy Cap,
Brand New Fuel Pump,
Fuel Pressure Reg Off Running Car,
Fuel Injectors Off Running Car (All tick and have a resistace of 12.6 Ohm),
Fuel Rail Look clean and is off running car.
Checked Air Flow Meter in smillier GQ with no probs found with it.
But still runs rough idle and blows smoke, Was way worse before but it's still bad now.
Any other things it could be?

smoke is blue? usually burning oil.. if it has been idling for a while and then does it might be valve stem seals if it does it constantly and chews oil its rings..
if its blackish smoke its running way rich.. get it tuned properly..

I don't know the fine details but I believe you can bridge out the
computer someway and it re-sets the all the settings or something like that?
that's all I have!
sorry

disconnect the battery overnight, see if it resets itself,
or purchase an ecutalk cable to plug a laptop in and veiw faultcodes and engine data.

I have an ecu out of a perfectly running efi tb42, took it out with the turbo install, your welcome to try it or buy it if your down traralgon way sometime.
Also have the airflow meter which can make them run like sh*t which you can try.

Pretty sure the fuel pressure reg runs off vacuum.. with the hoses off 294KPa with then on 214-255Kpa i belive. i havnt been home to check the hoses yet. Will do the reset tonight and see how it goes.
