Hey this may be a strange question,but when you turn off the O2 sensors to do the vve or maff cal is there still power running to them and the signal not given or is the power actualy removed from them. If so doesnt this place the sensors at risk of being burnt out. The reason I ask is on the weekend I was playing tying to set up the maff after changing the air intake and after i finished I got a couple of error codes relating to the O2. I have had the off 4 a week or so when doing the VVE previosly.
Thanks Ian
