Argo stalling poor fuel economy
Summary of the thread
A 2022 Fiat Argo with a gasoline engine is experiencing stalling at idle, poor fuel economy, and unusual smoke during acceleration, with the check engine light on. The suspected cause is a faulty mass air flow sensor, which can lead to these issues. The solution is to have the mass air flow sensor checked and replaced by a professional, which resolved the problem and restored the vehicle's performance.

So, your Argo had the same symptoms? Stalling, bad fuel economy, the whole shebang? What exactly was the problem, and how did you fix it? Was it definitely the mass air flow sensor, or was it something else entirely?

Yep, all those symptoms. It was the mass air flow sensor for sure. I'd suggest getting it checked by a professional. Could save you a lot of headaches in the long run. A defective mass air flow sensor will cause all sorts of issues. So I think it's best to take it to the workshop to replace the broken part.

Thanks a bunch for the advice! Turns out you were spot on. Took it to the shop, and they confirmed it was the mass air flow sensor. Cost me 365€ to get it replaced, but at least it's running smoothly again. Really appreciate the help!

Sounds familiar. I had a similar problem with my Argo. Is it struggling to maintain a steady idle? And has performance taken a nosedive? Could be your mass air flow meter (LMM). Has anyone checked the air intake system for blockages or leaks?
