My car (above) constantly shows the ems fault light but nothing appears to be wrong. I have taken it to local agent who checked it fully serviced it and the cam belt was hanged The fault code says it has a fuelling fault but emissions are ok, fuel consumption iis normal 25-30 mpg. (40mpg on motorway) The only small clue I have is that when initially starting from cold the engine seems to be over rich this seems more noticeable if I leave the air-con on. However a blip of the throttle and it clears straightaway. Any suggestions as to a possible cause would be appreciated. It is a 2.2lt omega sport with the ecotec 16valve engine
