Hi guys, I wonder if any of you can shed some light on a problem with my car? My engine management light came on last week, and although I have done multiple journeys since then it has remained on. There seems to be no difference in the engine sound, however I have noticed a slight flat spot when the revs are very low. This only started a few weeks back and may be a separate problem. Additionally, it would seem my car is running very cold. The temperature gauge doesn't raise much above 50c and the engine fan seems to be running most of the time? Thermostat?
