Hey guys,
Have had an ongoing problem with my ED Futura, for probably six months now. It's dual fuel and apart from using what seems to be way too much fuel on petrol, it idles and everything else just fine. But, on gas it really idles like a bag of shit, and the longer you leave it idling (under load mainly) the worse it gets.

Any ideas what this could be would be appreciated.

Cheers
Fludey

Mate,

Check the LPG mixer diaphram. If this is an IMPCO mixer then the diaphram should be easy to get to. Its in the big round thing near the rocker cover.

This is usually what goes first on the gas systems.

Thanks mate,
Would someone make it easy for the guy who isn't too bright??
Here is a pic of my Gas Unit, where would I find the diaphragm, and what will it look like if it's knackered??

On my EA with gas/petrol this use 2 happen, I cant remember what I did 2 fix it, but I think it was 2 do with the gas/petrol switch cause after that stuffed up and got fixed it was fine, ViGiLaNtE is probably right but!

The diaphram is a round rubbery looking thing with a stem in the middle of it, that mixer that you show there is a bit different to the one I had on an EF ( yes x-cab) . If your in melbourne you shouldnt have any problem for a gas company to take a look at it for you. And yes that switch can also be a problem, maybe losing it contacts with the terminals.

These are just ideas for you to check out. Hope you get them fixed as I know what its like when a car aint idling properly.

Ok, thanks guys, will get it checked out, just always worry that they will spend 2 days trying to find the problem, and charge me for it... SO I always like to try and fix it myself if poss.

Ok, if I could I'd like to ellaborate on my first post..
I will use heavy traffic driving as an example..
I accelerate, then when I come to a stop , the car almost stalls, then the revs are brought back up to normal, and will stay that way until I repeat the process again. Once again, it's only on LPG that it happens..
Maybe this means something...

Hiya Fludey,

This EXACT same thing happens to me - I have cleaned my ISC unit *that many* times, replaced the TPS, disconnected the battery etc, ummed and arrrred, done this and that - but still to no avail =\

One thing I am wanting to look at is the injectors - I don't know if this happens to you, but on ULP she idles rough, and power delivery is not smooth...LPG makes more power than ULP at the moment !!! Annnyway, I am wanting to check the injectors on my I6 to see if they might need replacing - I'm unsure if this is the case, but have you checked yours ? If so, I'd like to know more about doing that =]

Cheers,
Steve

Try disconnecting the wire to the fuel pump and see if it idles better with no fuel pressure --injectors may be leaking fuel when running on LPG.
