Got the temperature sensor today so decided to fit it, going along nicely when I realise one of of the screws on the ignition coil is burred try moving it but no go, sit back look at it and see it held on by a frame with two bolts so remove that and then the temp sensor put the new one on hurredly and doing it up and think that it should be tight enough but I pop home and get a Torque wrench (one I've had for ages) set it to 14lb ft and proceed to tighten and tighten, I am now thinking this has to be tight enough and should have stopped but instead of popping home again to get a smaller more expensive and accurate Torque wrench (which I couldn't find earlier) I press on and then you know what happens I of course break the bloody sensor! So refit the old one and thats another £70 down the pan. No fool like an old fool. Had I been watching anyone else doing the same thing I would have told them to stop and revaluate. I am trying to blame the Torque wrench for it's inaccuracy but I know deep down who's to blame, it must be those leprechauns I saw on the way to work!!
