I'm probably talking bollocks here but check that airflow is not obstructed (filter etc). I would also check the throttle body and butterfly. If it's struggling to breathe the ecu will try and chuck more fuel in to compensate. Check fuel pressure and ensure its not intermittent.
Hi all, new to this forum thing. Currently using my 2011 Gordini (no. 100 according to the plate) for commuting whilst building it up for road rallying. I think it may have a chequered history but it's straight and alot of fun (if anybody knows of it's history any info would be appreciated)...
