Hi all,

I'm in the process of purchasing a 98 GU Patrol from my parents which runs on LPG/petrol. It runs perfectly on LPG, however on petrol its as though its limited to 2500RPM, even with your foot to the floor.

We've replaced the fuel filter, drained the lines, and replaced the spark plugs. Fuel pump is working fine.

Does anyone have any experience with this or any idea what it could be? In the past couple of years it has been run almost exclusively on LPG so I'm not sure when the problem started.
