Last week when off road, I had to climb a limestone track to get up off the beach. Pretty steep with a nice jump up about half way up. No problems, 1st gear low range, 16 psi in my brand new BFG all terrains, I basically just idled up, no throttle. I get to the top where it flattens out, as I apply throttle.. Well I've got none. No throttle response and a louder than usual rattle under the bonnet. Stopped for about 20 seconds and it was as good as gold, no signs of any issues under the bonnet. Ran fine after that, it's almost like it starved of fuel? I run twin tanks and for some reason the last owner has plumbed in a EFI style in line fuel filter on the supply line from tank to engine. Any issues there? I have the EGR mod also, couldn't see it being that, my D22 is the ZD30 with 65k on the clock..
