GQ/Y60 97 4.2 EFI LPG gas problem
HI all,
My 1997 GQ 4.2 ltr petrol on gas.
The patrol ran out of gas and as it did backfired. Since it backfired it is running like a shaking machine. I've replaced the diagram in the secondary gas unit (not the main gas converter), replaced plugs, leads, checked distributor, replaced the sock that blocks the holes in the joining pipe and made sure the air box is sealed. I had it to a mechanic and they don't know why it is running like a charf cutter either. Need help?
