Sorry for the delay, have had to do some work. Find the ECU, probably beside the throttle pedal behind the trim. Remove trim, make yourself vey small and double jointed and remove the multi connector to the bottom of the sec, it has a small retaining clip furthest away from you. Once removed leave for 10 minutes or so (gives you time to put plasters on the cuts you have probably just recieved) then re-connect etc. This should reset the ECU and remove any recent settings it has adapted too. Worked for mine, although not perfect is a lot more drivable.
