My 1992 LPG'd 3.9 has started to stutter whilst running on gas. It happens under heavy acceleration and seems to stutter through a certain rev range until it clears at the top and takes off nicely. It doesn't happen on petrol, just on the gas. Does anyone have any suggestions? Thanks STU

Hello everyone. What can I say except hopefully we can meet up in the future for a natter:eek: . Cheers STU
