LPG S60

[Wander]

Hi all!
I've had a "Bi-fuel" S60 for a while now and it's a gorgeous (and more important, cheap!)motorway muncher but has recently started being a bit "jumpy" at 50mph....but only when on LPG.
The local dealers have given the LPG fuel injection a good clean out and no better. They now recommend a new one, at £750!!!! Ouch!
Does anyone have any expeerience they can offer/ recommend. I'm in the Bristol area.
Many thanks,
Alex

all that is needed is the gas distributor cleaning out,volvo do a service kit takes about 2 hours to do,should cost about £250.
