an alfa mechanic was talking to my dad once about the modern cars, with their ECUs and all. he said they sometimes create trouble themselves, for example: (and heres the interesting part): once there was an alfa which was working fine, sort of. but he needed/wanted to clean it's throttle body. so he did. when he started the car it didnt run well. as far as i know, it had fast idle too but i'm not 100% about this. turns out, the dirt inside the body was detected by the ECU that it was lowering the flow, so the ECU adapted itself for this dirt so that the car still works fine. then when he cleaned it, the ECU was still set for the dirty throttle, because it needs time to get adapted to the system. so basically the ECU needed to be reset. he did, and the car was fine.
now i dont know if you need to take it to the delaer for the reset, but if i were you, i'd remove the battery for about 15 mins, that should reset the ECU.but maybe it needs a REAL reset, done with special interface
dont know if this makes sense, probably not
