Hi, I have recently become the owner of a 2002 S80 Bi Fuel.
I have a constant problem with a misfire on gas, it happens most strongly at 2000 rpm, but starts at around 1800 and finishes at 2200, so Basically cruising at 60mph is the worst time.
This is only whilst running on Lpg and only when cruising or driving steadily, at lower revolutions there is no problem, and at higher speeds again no problem, under load or heavy excelleration no problems.
Would like to hear any ideas or from anyone that has had and solved the same problem,
i have searched and read several similar problems, but nothing exactly like this.
Thanks in advance.
