Gidday, Jack here, I've recently become the owner of a beautiful 2011 FG Turbo ute, bog standard (and it will stay that way) but the fuel consumption is not great, 15+km/l in a small town, and I'm driving it like a nana, I'm thinking O2 sensor might need a replacing, but that leaves a question, how many sensors are there? I've got conflicting info, some say 1 others say 2, can anyone give me a definitive answer? Are there 1 or 2 sensors?
Cheers
