Check the fuel pressure in the fuel manifold as if it is too low then the injectors will not be working properly. Have a compression test done to check valves and valve timing. Low compression may be valves or the timing may be out . Check the air gaps on the crank and camshaft sensors and clean out any grease or dirt in the area.

My Vy commodore battery goes flat over night RACQ jump start me they checked the alternator it's not the alternator No lights have been left on Does anyone know where the power could be draining from?

Hi Jessica, A fully charged battery is 12.6. The links below are a couple of youtube video on how to find out if a car battery has a power drain, The 1st video starts with the guy loosening the negative lead to the battery then turns the multimeter on and sets it to 20 DC, plug bottom of lead to current mode and places 1 multimeter lead on top of the terminal inside the negative lead and the other multimeter lead on the negative lead and wiggle the negative lead off the battery, The current being drawn from your battery should be less than (5.0) 50 mille volts..... The reason he takes the negative lead off after connecting the multimeter this is to save any codes from the car as technically the battery isn't disconnected.. Also, There's videos down the right side you might find helpful as well.........CHEERS..

2004 vy commodore. What is temp sender unit resistance?

it is a variable resistance that changes with the coolant temperature
when it is cold ,that is the highest resistance and when it boiling ,that is the lowest resistance
It is the variable resistance that gives the readings on the gauge.

How do I home tune my 2004 vy Commodore

the engine is continually being tuned by the ECM program and requires nothing from you. If you feel there is a problem then run the fault codes and fix what ever comes up. Plugs are not consumed as in the old cars because the voltage is so high and the current is really low that the electrodes do not burn out. Leads you may have to replace as the insulation cab break down but all else is controlled by the ECM program
