The only way to be really sure is to get it connected up to your laptop with FiatEcuScan and see what codes its kicking out - you would also then have the option to erase previously stored codes and start 'fresh'.
Doing a throttle reset would also be a very good idea IMO. Procedure detailed on here if you search.
Good luck.
