The sensor at the back of the block is the oolant engine temperature is a 2 pin sensor .Green in colour with 2 push on plugs .This can cause problems .It sends the message to the ecu to set the fuel for the hot or cold mixture .If faulty it can send the info to say its hot , and then ecu will lean out the mixture. Or can work the other way, engine could be cold and the mixture will need to be made rich, but ecu had no mesage to tell it to do so and its keep lean . So worth a change if you can replace it . Tight to remove it ,but it can be done .Have you an economy gauge on the console? If so is it on the far left at start up?
