Any thoughts on this. History is that I have had a problem with lack of power on cold start ( especially day after a long run) with my 2010 Ducato 2.3l Motorhome with fault P0638 Throttle Actuator Control Performance Bank 1 coming occasionally. More so after a long run the day before. Another fault developed where the throttle would stick and engine raced on changing gear. Fiat professional garage diagnosed failure of ignition CPU which was changed out. I still had original fault on my next time away and Fiat garage said I required new Throttle body and Engine ventilation valve as oil was passing through. This was done but I still have the problem of no power on cold start for first 10 minutes and fault P0638 is coming in regularly. Any ideas? As im fed up throwing money at the so called Fiat Professional garage.
