hi guys quite new to this ive had my clio 172 cup 53 plate bout six months and today was driving along and noticed car was feeling a little lumpy and rough the warning light above the over revs light was flashing then going out then coming on again ive recently had spark plugs and ht leads replaced because one off the plugs decided to spit out could it be lamdba sensor, cat or coil pack appreciate replies

hard to say really, but could be map sensor or lambda. Have you changed the coil pack on it? might be on the way out?

hi havnt had coil pack changed yet but took it to my mates who hooked it up on diagnostics and it read high speed fan circuit relay and then misfire cylinder 3 thats the one where the plug come out and i had to have it helicoiled thinking might need new head?? annoying

Defo coil pack, eventually itl tell you to stop, common on Clio sports due to coil pack sitting above exhaust manifold
