Apparently they are readily available spare parts, fairly inexpensive as major electronic components go, at around $300.
The unit in my car governs both electrics and sparking, fuel / oxygen mixture as well as the automatic choke... so here's truly hoping it solves the problem.
It's gradually getting worse / less bearable... I can't afford a new one if my old kicks the can... it's not likely though, I believe I am not far from ironing out this bug.
Oh God please let that be true!

What make, model, year, and engine are we talking about here, Scottsy? I might be able to dig something up on it. A scan tool can be hooked up to the module to record a movie of the data stream from all the parameters (sensor inputs and outputs). A tech should be able to use this to determine if the module is indeed fried. Also might shed some light on what else is going on.

Unique modeal to Australia...
Built with a japanese designed body shell and suspension components, but fitted with a Holden (GM) Family II four cylinder engine, capacity 1.6 litres.
They built these engines for export, so there might be a bit of info hanging around on them. I believe they were still building Family II engines for Daewoo and other cut price car brands in South East Asia till around the early to mid nineties.
Would appreciate any info you might be able to dig up Strat, but i don't expect you to go to too much trouble. It was a unique model to Australia, known here as the N13 Pulsar range. Engine also came in a 1.8 litre capacity.
Also sold as the Holden Astra on the local market with no mechanical differences.

What's the year? That and the VIN and I might be able to turn something up. You probably know where the VIN is, but it should be visible through the windshield on the driver's side.

...pleases stand back, the Universal Master Mechanic is on the case...
'But Mister, it's an Australian car!'
'Doesn't matter son....I AM the Universal Master Mechanic!''

Does it have wheels? j/k - My knowledge is actually somewhat limited, but... We aims to please!  |

It has a set of wheels which would be hastily pulledc from it and sold separately if it were to be sold.... hahahahahaha, they're too nice to sell with the car, unless what I was getting was something better. :-)

So get the VIN and the model year to Strat, Scottsy! I'm interested to see how this plays out. Can the Universal Master Mechanic solve the case? ;D

Strat, might be calling upon your expertise should replacing the engine computer on Saturday prove unhelpful in resolving the issue... although I am feeling reasonably certain the ECM is the root of my evils... I've been wrong about this little problem before!
Will give you details about the VIN, etc if my mission on Saturday fails... fingers crossed, eh??!

Mission was pretty successful, I think.
Computer was replaced, still had the same problem with engine cutting out, starved of either oxygen / fuel.
Pulled out fuel filter and found that a hose leading to the fuel filter had perished, and the fuel coming out of the filter was black... as well as this I ran it to an almost empty tank a few weeks ago, putting a whole lot of junk through the fuel system... we hacked open the old filter... it looked terrible.
So I am pretty sure my problem was caused by dirty fuel and perished rubber fragments and a filter that had become so clogged with shit it just couldn't cope.
Have replaced filter and I am experiencing much better pick up, virtually no flat spots or blow backs... I have a bit of rough running and an occasional whiff or air blowing back through the air filter as the muck and junk works its way out of the system.
I have put a fairly heavily concentrated injector cleaning fluid though the fuel system and it seems to be smoothing things over... I think I need to take it out for a good hard blasting on the freeway to really clean her out, especially the freeway near here whioch has lot of steep inclines, should push out the last of the gunk and even things out a fair bit...
Needless to say i am a happy guy... no major issues with electronics, etc, just a bit of shitty fuel and a crappy filter.

That's good news, Scottsy. It's always good to start with the basics - often overlooked! Yep, run her through her paces to get her good and hot and blow the carbon out of the cylinders.

She's coming good already just doing urban running... has only come close to stalling like before once, and i am expecting a bit of activity as fragments of rubbish owrk their way out from the injector cleaner I have put through... overall feeling nice, idle is settling down and smoother, and she feels more assured.... give her a few weeks and a good blasting through herpaces, and she'll be almost good as new!

Gawd, I bet everyone's getting sick of me and my stupid car by now.
More work to be done... professional injector cleaning required I think. Been running better but today it struggled with the air conditioner turned on, and in fact everytime the compressor cut in (it cuts in and out depending on engine load) it was a near deah experience from the engine, and you guessed it, it was accompanied by a big gasp of air through the air cleaner assemby...
So now that all the lines are clean, the electronics are all straightened out, the fuel pump is fine, giving adeuqaute pressure... its got clean fuel, it's got fuel system cleaner running through it
The very last card on the table is the injector is clogged up like an old man's bowels...
This HAS to be the last thing going wrong...

Professional injector cleaning might help, Scottsy, or not. Also, some injectors are not to be cleaned - you just have to replace them (but not usually true on a throttle body like yours). But the A/C compressor puts a hell of a load on any 4-cylinder, especially one with high mileage (guessing?), so I wouldn't be too concerned over a shudder or two, at or near idle. The idle might need to be a little higher... Roll it off, dude!  |

Yeah, but what concerned me was its absolute inability to move when accelerating at the lights... seriously the thing wouldn't shift it's butt... and i had the pedal pretty far down.
I dunno... it still didn't seem to add up, and it shuddered like an elephant shaking something off its back at around 100kmph.... 60mph...
Still not feeling right to me... I just dunno what do with the thing anymore.
Spare parts anyone?
