VS Senator V8 Idle Probs - Duel Fuel

[deserthead]

Hi all,

I've got an issue with my Senator.
We got it converted to LPG about a month ago.
Every since it was converted the idle has been high.
Roughly 950rpm in gear and 1100 - 1200 rpm in neutral/park

It was idling fine before the conversion.
700rpm in gear and bout 850 in neutral/park.

It has since been back to the install place, but they seem to think its normal. . . . I've given up on them.
Stupid Townsville, limited choices. . . . .

So I've done searches here and elsewhere and found no answers to help me as yet.

I have cleaned the throttle body, replaced the TPS & IAC and reset the idle.
I have also checked for vaccum leaks but have not found any as yet.
Throttle cable is not tight and I have checked the butterfly valve and the idle screw also.

Atm im only getting between 200 to 250ks per tank of lpg.

So im after any ideas anyone has.

Cheers!!

take it to someone who knows what they are doing, changing fuels shouldnt affect the idle speed
