Check the earth connections.

Hate to tell mate but your ecm is failing. There is an internal earth that is failing. Next time it wont start try this pull out the start relay and bridge two of the pins with a peice of wire with your keys on the run position. The car will start... another tell tale sign is the dash saying very low fuel or fuel gauge error contact dealer. Even when there is plenty of fuel in the tank.
If this is the case your ecm will not be long for this world... sorry.

I have a automatic 2005 vz ssz ute, tried doing a burnout on my mates pad but wont skid, with foot on brake and foot flat on gas she will only rev upto about 1500rpm and kind of shutters when letting of the brake like traction control is kicking in but the ute doesnt have traction control in it I've been told it's because its has some sort of anti abuse programmed into it? But got told it will skid if you pull out the abs fuse, any ideas on how to get it to skid. Cheers

Alloytecs can be noisy *IF*you get the horrid timing chains problem where they rattle on start-up.
Otherwise, Alloytecs are silent engines; only the SIDI DI engines in VF Commodores are truly silent and quiet running.

Please ensure stereo volume is turned up to the maximum possible setting before attempting to start the vehicle. This is vital.

Hi Mick, I read that you're having problems with your Holden Commodore VZ particularly with the "low idle, stall" which could likely be a computer problem (mix up) after you've "changed the battery", (I'm wondering if your vehicle is coded with a 4 digit number? and is the main centre screen on dash showing any message asking for the code?) Or it could be your computer may need to be remapped (tune) and if you've tried that and it hasn't worked, maybe your car needs to "relearn the idle"and best advice is to take it to a trusted Holden dealer.

Wrong advice complete nonsense. Disregard... clean throttle body with correct cleaner and clean rag. Perform throttle body re learn with tech 2 or equivalemt scan tool and then reset long term fuel trims. The above advice is a classic example of someone saying something that doesnt even have any basis in reality. NOTHING said there is even POSSIBLE on that car they simply do NOT do what he has described. I have programmed over 1000 VZ v6 alloy techs over 1000 cars easily. This is how I make my living. Sorry the tb relearn does exist so the last thing he mentioned is likely the actual problem but all that other stuff is tosh...battery mixing up the computer. .bah NEVER has the bosch ME9.5 had this happem to it. A short to positive will more than likely completely fry it but you would have seen it arc out or smelt melted wiring. NOT LIKELY IN THIS REALITY. needs a RE map ....wow thats a good one.
So suddenly the factory fuel maps need changing? Wont that change the emissions? ...yes ...isnt that...illegal?...yes...

When you have coolant leaking from the front of your engine from mid range is it the water pump or gasket? How can you determine what it is? My car overheated last night. I've topped it up but it seems to be leaking everytime I run my car. The coolant runs onto my belts, from the bottom left to mid range of engine.

Hi Matt. That's a bit unspecific.
ALL lights? Parking and headlights? Do the brake lights work? What else doesn't work?
Does the interior light work?
The headlights are on a different circuit than the parking lights, so unless its something catastrophic, I would say some lights do work?
Maybe check the fuses? But give us some more details.

William

Hi Matt, if it's lights it is definitely an electrical problem, get it checked with an auto electrician or as mirrabucca mentioned maybe check the fuse or give some more details.

I have a 2004 vz ss every time I put it into reverse it blows the blinker fuse but doesn't do it in any other gear I can drive around and use the gears and blinker, also if I blow the fuse I still have hazard lights I also have no reverse lights either since this problem started

1: What Hammerhead said...
2: I would start at the reversing lights. Anything damaged the tail light/reversing light area inside the boot? Maybe someone threw something into the boot and it damaged some wiring? You might have a shorted reversing light bulb (very uncommon).
