I have encountered a problem over the last few weeks in as much as I have noticed an increase in temp and the engine does not respond well, when looking under the bonnet no signs of overheating were noticed, on switching back on the ign the gauge went slowly back to normal (30-40) sec started up again drove off normally it has done this a few times without any signs of overheating!!! does the engine reduce power when a temp overheat is displayed on the gauge any ideas what may br wrong
many thanks jf
