Now i know this is a ford site but if i ask the 'other' side ill get hate mail for the next month or two. Long storey short...bout 2 years ago my mum, even though i told her not to, brought a VS commodore, it brought shame on the family (hehe). Anyway..she brought it cos of the 'nice' color and the fact that it was duel fuel. Now I now that holden and gas dont mix, but she didn't.

Anyway, this problem has happened two times while ive been driving and once with her and its bloody dangereous!!
It only happens when on gas, and when its happened to me, I will be braking to turn into a street, so rpm is bout 2000 or so. Then just as i was about to turn into the corner the bloody thing stalls and cuts out!! Being an automatic that means the power steering cuts out and you have no control except for braking.

Luckly I live in a fairly rural town so on these occassions there was no traffic coming the other way, but I went straight off the road into someones nature strip on the other side!!

Has anyone else heard of this? Cos let me tell u its not a nice feeling

Unless Holdens are different to most cars the auto's got nothing to do with it. There's a separate pump for power steer and when engine dies it stops pumping and you've got extra heavy manual steer, which seems even heavier because you're used to power. Should be able to drag it around, although I've run wide and got a fright a couple of times in XF when same thing happened in normal city driving. Definitely dangerous it if it happened when you're pushing it. If you can't stop it cutting out, you could always buy your mum a season ticket to a gym and get her arms beefed up!

Does it happen every time? Or only after you start it when switched over to LPG? The reason I ask is that the system that most late Commodores run is electronic and starts the car on petrol until about 2000rpm when it switches over to LPG. It does this by switching off the injectors(petrol) and then switching on the LPG solenoids. When this happens there is a huge, no kidding, flat spot which can be very off putting if you happen to be driving. Mum's VP has this system on it and it has the same habit which scared the hell out of her the first time it did it. We took it to the dealer that sold the car who then sent it to a gas workshop who said it was normal. I then took it to a mate of mine who used to install the system and he said that it was normal but our car seems to be worse then most. Now the car is in Queensland and the system has been reset by an authorised installer. It still has the flat spot but I have been told that it is no longer as savage.

My nan and pop's VP did the exact same thing. Nearly killed em at one stage . Fortunately the car has been sold(thank god!!).

One solution you may find is, and i know its not ideal, is switch it over to petrol when decending hills or going into corners.

Another solution, far better, is sell it and buy a falcon

its only happened a couple of times...and only when i go to turn into a street, so far anyway. Its a factory installation so I dont know whats going on. We took it to a gas 'professional' and he doesn't have much of a clue either. I'm just not gonna run it on gas, its just to dangereous.

Trust me, I told her not to get a holden, but i couldn't go with her to buy it. It was either the Vs or a bloody Camry..at least the holden has a bit of go.

Wonder if there's a power steer and/or speed sensor involved that's supposed to increase revs at low speed for more power steer assist and they're not interacting properly with each other or ECU or LPG system? Run the fault codes and see if anything comes up. Don't ask me how to run fault codes on Holden 'cos I don't know.

 

[FoMoCo4eva]

yeah ea s..you could be right...we took it back (again) and they said they would run some test ont he computer..but buggered if if i know what that involves..they disconnected the gas switch to see if that was faulty but that did nothing...i just think the problem is the brand...lol

 

[EA S]

They'll hook it up to something (you can do it on Ford with just a testing light) that'll throw up codes that identify sensors or whatever that aren't giving readings within correct range and probably past running faults that have been stored in memory, and that at least isolates the problem area, but not necessarily the cause of the problem e.g. if a sensor comes up as a problem it mightn't be that part which is defective but some leaky vacuum line connected to it. Let us know how it goes.

I have been having the exact same problem in my EF.

Found a solution last week. The problem was air coming in through the cold
air scoop at the front when off throttle. Which is basically whenever you
are slowing for a corner or traffic lights.

I simply removed the cold air snorkel at the front (that is if the VS has one?) and it instantly fixed
the problem, its a bit of a dodgy fix cos then you lose the cold air coming
into the engine. It may only be a problem on certain types of gas systems.
But after taking my car to 3 gas specialists this is the only thing they
could come up with.

I thought screw it and took it off, you may lose a little bit of power but
at least your not gonna write yourself off!

Try Ian Reid at "Stay Clean Conversions" in Keysborough on 9701 5211. He would have to be the absolute guru when it comes to LPG. Mind you, he isn't much of a fan of Holdens (um.... he hates them), but he does acknowledge that some people have lapses of intelligence occasionally!
