Try doing a fault code check which is easy: http://forums.justcommodores.com.au...22307-checking-error-codes-vr-vs-revised.html Car shouldn't run at all with 10V at idle - are you sure about that? Also how many Km's on the car...also history of car etc. More info always helps.
V8.. Its got 180 thousand kms, car is stock standard only parts changed are the new alternator and battery, it all started after the electric thermo stopped workin and could not get it workin again, its had a conputer put on it to check codes an everything was fine but the bloke it is doing something odd and using alot of fuel but they dont no why
When you say electric thermo, do you mean the A/C thermo fan in front of the radiator or have you had thermos installed to replace the clutch fan? If it's the A/C thermo then you should disconnect it to see if that makes a difference - you may be getting some sort of voltage/current loss there. There is a connector on the front at the driver's side about half way between the radiator and the guard that you can use to disable the thermo fan. Failing that you should take your car to an auto electrician.
