Ford Falcon AU Duel Fuel

I start the car on LPG, it almost feels like stalling.

Where should I start checking first?

this a dogy way of fixing i mean masking the problem u can tighten the throttle cable a little which will bring the idle up but dont go overboard or you could pay 98 bux and take the car to ultra tune i no i no ultra tune any way they wil hook computers and things to ur car and se wat the problem is i hope this helps..

It just needs to be re tuned, I had mine done after a couple of thousand Kms as it was idling low, been fine since. most of them are easy to adjust if you know what you are doing. but you can never get it as good as the pros as they have all the emmissions equipment and everything else.
