I was out tonight giving the clio a bit of shoe and all of a sudden the power really dropped of and the engine started making a strange noise - almost like something was rubbing. I pulled over and the engine was struggling to idle. I knocked it off and restarted it but it was only just idling then cut out and wouldn’t respond to the throttle at all. Eventually i got it going by starting it with my foot flat and managed to drive it home but there was hardly any power and between 2-3k the engine seemed to be tapping. There's no management fault light or codes, anybody got any ideas?
