Geday, not 100% if I’m going about this the right way as I never use forums and this is new to me. So plz be kind so I just bought a duel fuel VR Ute, fairly standard gas setup that was done in 2006. I was driving, ran the gas completely dry, switched to petrol. The car started driving like crap, it was studdering and carrying on. I thought I’d done a center bearing on the driveshaft. Changed that, obviously wasn’t the center bearing, runs like crap still. It idles okayy.. but underload it splutters n pops n back fires, and I mean BACK FIRES. Can hardly get it through the gears, I.e un-drivable. I’m quite unknowable when it comes to gas. I’m going through the fuel system and making sure all is well, filter, injectors ect. If anyone has any advice, that would make life much easier. Thank you.
