Hi all

have done a few more miles on petrol today with the injector cleaner in and I think she's now soerted.

She's running really well on petrol and ok on gas with now mil light etc.

She's 95% ok on gas so I will change the filters and give here a check over once the new filters arrive.

Cheers ...

hi all

the problem persists even with the injector un-plugged so its definitely leaking. The car changes to gas within 60 seconds even on a cold
start so the petrol injectors see very little use.

I added some injector cleaner to the tank and did 40 miles on petrol yesterday so will see if its any ...

hi all

have done a bit more in this

I read the fault codes which showed misfire no2 cylinder which confirms what I saw on the plugs.

Popped it all back together and got it running on gas. I then clamped the petrol feed to the injector rail so that it could not get petrol and she immediately ...

hi all

I have started doing some work on the saab this morning

First thing I found was the oil filler cap o ring has failed so there's effectively a vacuum leak so I will replace it.

I have pulled the plugs and numbers 1,3,4 are all perfect but number 2 is sooty. I don't think lpg leaves sooty ...

hi all

its a Koltec system

Its a factory fit system and has worked well.

I have picked up a new set of plugs for it so will pop them in tomorrow.

I have sent Simon an e.mail, I have used him before around 8 years a go.

Hi all

I have a 2006 Saab 9-3 with factory fitted dualfuel.

She is currently running rough when on gas. On petrol she is perfect.

When on gas she has a slightly rough tick over and is down a little on power when driving. Although she has a full service history from new, i'm not sure that the gas ...

hi all

I have a 2008 Proton Persona which I converted to lpg 18months ago using
an esgi system.It has run faultlessly for the last 25000 miles and passed two mots without
a problem.

I now need to have it checked over and put on the register so that I can sell it on.
Could someone recommend an ...

I have a brand new Landi Renzo feeder stepper motor for sale.

Its for the IGS system and can be used on either the low or high volume side.

They are completely unavailable in the uk and most of Europe.

Looking for £50 for it inc postage.

I also have details of a supplier of spares for this ...

:P hi all

have now sorted this

have replaced both feeder stepper motors with new ones from Poland and
reset the idle enrichment on the ecu and she's now spot on.

I have one brand new stepper motor left as the supplier sent me three in error.

If its of use to some one then you can have it at ...

hi there

Ihave recently bought a rover 45 with an igs system fitted

it runs and drives spot on on petrol and gas.

I have serviced it and found the connector for one of the gas stepper motors is
disconnected - the high volume one.

When I connect it back up the car stutters on acceleration but ...

hi there

I fitted an esgi system to my proton gen2 earlier this year and it has run without fault since fitting.

I need someone near wakefield to check it over and put it on the register.

Thanks - mike

hi all

just an update on this

have now done aprox 1500 miles since converting.Had to adjust the gas map around the
mid load range as the engine management light was coming on and the petrol ecu
was logging mixture to lean.

Car is now running superb,41-42 mpg on gas,paying 62p/ltr so less than 8p ...

hi all

have now got this sorted

number 4 petrol injector was wired the oposite way to the other 3.I didnt spot this when
I wired up the lpg system.

The cars now running fine,1.5mm nozzles,1.35ish on the gas pressure,calibrated fine
with a correction of 1.77.I may drill the injectors to 1.8mm to ...

hi again

just a thought about the map set up

I have a drilling at one end of the manifold that was connected to the fuel pressure regulator.
I have teed of this and run to another tee with one connection to the map sensor and one connectionto the vapouriser.Map seems to be 9ish kpa at idle.Does ...

hi

re-drilled the nozzles to 3mm this morning and ran auto-cal again
and the conversion has gone to .34!

I think the nozzles need to be smaller.

When I use the nozzle size calculator in the esgi software I set the type to valtek 3ohm
the engine powere to 110hp - should this be kw?

and the max ...

hi there

have looked on the lpg screen on the software and its showing the lambda to be on th yellow
but only just.

Is this rich or weak ?

I have a 3mm drill so could re-drill the injectors if its running weak

Thanks

mike

Its currently running with the injectors drilled to 2mm and the gas pressure is 1.3-1.4 bar.

Its a 1.6ltr with 110bhp.

It seems to be running ...
