sometimes when its really cold, when i start my car misfires then clears as it starts to warm up, does anyone know what this maybe :confused:

Could be dirty connections on the ECU temp sender. Could also be dirty connections to PTU unit or even dirty injector connectors. When its cold eveything shrinks and the connectors make a worse connection than normal, too much corrosion and its enough to stop them working alltogether...

worst case senario could be the values, if you find thecar starts to get harder and harder to start each time then you may want to take a look at this area. I had this with mine, started running lumpy when cold and then got progressivily harder to start. Had to have all the valves reseated.
