What plug gap do you run in the Crewie Mick? I did the plugs on the ute a while back and set the plugs to 1.5 same as what I do with the Calais. Everything I read on the net says around 1.1, have I gone too big on what is essentially a stocker (except for full exhaust)? Just trying to eliminate possible causes for the fuel consumption. I will give the MAF a good clean with contact cleaner also prior rushing into changing 02 sensors. My latest test at the bowser returned 17l/100, and that was nursing it (ie not going over 2k most of the time).
