Missed the last gb, and got one anyways. THing is, at start up, the idle fluctuates a little, up and down, but not enough to move the needle on the tacho which always reads at approx 800rpm. Once I drive it a bit it settles down to a steady idle. What is this? Its only since I have fitted the por-flo, is it to do with calibration?
