Barchetta engine power loss
Summary of the thread
A 2005 Fiat Barchetta is experiencing reduced engine power, with a scan tool indicating a generic engine malfunction error. The issue is suspected to be related to chip tuning performed by a third party five years ago. It is suggested that the tuning may have stressed a component, leading to the problem. A professional diagnostic and remapping at a workshop is recommended, which ultimately confirmed the tuning as the cause, requiring a remap and sensor replacement.

I read the code, but it's a generic 'engine malfunction'. The tuning was done maybe five years ago. It's been fine until now, which is weird.

A generic code with tuning in the mix definitely points to that being the problem. It might have stressed some component. Best bet is to get a proper car diagnostic at a workshop. They can probably remap it correctly or undo the tuning.

Took it to a shop. The tuning fried something, needed a remap and a sensor replaced. Cost me 180€. Thanks for confirming my suspicions!

That sounds like dodgy chip tuning. Have you read the specific fault code? Knowing that would narrow down the possibilities. Also, how long ago was the tuning done?
