After Gas Conversion

[JSCOLLO]

Hey Guys,
Just want to know if anyone has expereinced the same problem on a VY II 2003 Exec. I just got the car converted last week to LPG and last Friday i thought i would run it on petrol to lubricate the engine. When i was on petrol it was idleing rough and stalled and pulsates whilst i am sitting at the lights.
Everyone that i have spoken to has said that it could be the leads or the plugs. The funny thing is that when i took it back to the conversion place they said that it was fine.
I told him that it was ruuning fine prior to me taking it in there and now it is idleing rough. I now have to wait till next Friday to take it in and when i called him Monday morning to advise him it was still doing it he said he will change the plugs and see how it goes. It is at 88000 kms and by coincidence the service book it advises that this service i need to change my plugs.

Has anyone else experienced the same issue. Would love to hear how to fix it

I would have thought if it was plugs and or leads it would play up more on gas rather than petrol.

Yeah and thats the problem, because its not happening with Gas at all just petrol. Do you think that it could be the leads also as they changed to new gas leads.

Dirty fuel filter?? Some of the dirt could of settled as it hasn't been used for a week.

Guys just to let you know, when i got the conversion the gas people took off my spark plugs and made it a .5mm gap instead of a 1.5mm he changed the spark plugs after and its running beautiful. Thanks for all your help guys.
