    running at a lower temp on average lately (80-85degC) and mpg seems to have dropped. Can't be duff temp sensor as it was only replaced in may. Any ideas or quick checks?

    as I said, coolant temp sensor was only replaced in may, so can't be that. nothing else tells the ECU water temp (2 feeds from the temp sender - 1 to ECU and the other to the dash display)
